     TECHNICAL FIELD 
     The invention relates to apparatus and process for integrating the order and delivery of retail merchandise and particularly to an automated system for integrating point of sale and warehouse processing functions in the selection, order and delivery of merchandise. 
     BACKGROUND OF THE INVENTION 
     Many computer-based systems have been devised for automating various aspects of the shopping process. Electronic inventory, product scanning and order processing devices are available in many retail establishments to increase the efficiency of transactions and thereby improve service to the customer. Such equipment is utilized in some stores having a format in which the retail point of sale and merchandise warehouse are located in a combined facility. This format is often operated by placement of just one representative sample of the especially large items in the retail area, with the remainder stored in the remote warehouse portion of the facility in effort to maximize the use of display floor space. When an item is purchased, the customer must wait while the merchandise is routed to a designated pick-up and loading area. 
     While known computer-based automation systems have reduced the cost and increased the efficiency of handling retail customer transactions, numerous disadvantages and shortcomings exist in their application to the combined point of sale and warehouse retail store format. A system is needed in which the point of sale and warehouse processing functions are coupled and operate in real-time support of each other. Elements of the system need to be integrated to provide a highly efficient operation which reduces the number of required sales, warehouse and check out personnel, and which improves the timely communication of information between such personnel and to the customer. Improvements in automation of this type are required to establish an information-based flow of customers through a store which maximizes the customer&#39;s shopping experience. 
     SUMMARY OF THE INVENTION 
     The foregoing problems are solved and a technical advance is achieved by method and apparatus for processing merchandise sale transactions for customers in a point of sale and warehouse facility in which a point of sale computer system is coupled with a warehouse computer system, and the two systems operate in support of each other. In a departure from the art, a series of interface programs allow the warehouse processing functions to cooperate with the point of sale processing functions in order to provide an efficient merchandise selection and delivery process. 
     A further enhancement to the purchasing process is realized with the use of hand-held, pen-based sale transaction computers. These computers are utilized by store personnel to assist customers in their buying decisions. The computers communicate with a controller of the point of sale system through radio frequency transmissions, and make the entire sale transaction record available to the customer and the store personnel on the merchandise display floor at the point of decision. Using scanning technology, the sale transaction computers read a unique membership card which identifies the customer, and a universal product code label which identifies the merchandise to be purchased. Upon scanning the merchandise, information is displayed to the customer regarding the merchandise and regarding delivery options for the merchandise. The customer selections are entered into the sale transaction record, which is stored in the point of sale system until the customer checks out of the store at a check out area and pays for the merchandise. Once the merchandise is selected at the point of decision, the point of sale system sends information to the warehouse facility to enable the merchandise to be picked from the warehouse and sent to the delivery location, thereby minimizing the wait time required for the customer to take possession of the merchandise. When the customer elects to check out, all transactions can be recreated electronically and tendered in the shortest possible time. 
     In a preferred embodiment, the apparatus includes a main store processor having a database for storing customer identification information and merchandise information and which processes sale transaction records for customers. A point of sale system coupled to the processor has a controller and at least one pen-based computer in communication with the controller via RF transmissions. Program instructions respond to entry of the customer&#39;s identification number and to entry of merchandise identification numbers to build a sale transaction record of selected merchandise for purchase. The program instructions display merchandise information and enable selection of merchandise for addition to the sale transaction record, display delivery method instructions and enable their selection for addition to the sale transaction record, and transmit the transaction record to the processor to effectuate warehouse delivery of the selected items according to the selected delivery instructions. A warehouse system coupled to the processor generates an item pick request in the warehouse to locate the selected merchandise and to initiate delivery according to the selected delivery instructions. A check out system coupled to the point of sale system accesses the sale transaction record and accepts payment for the selected merchandise. 
     Automated systems are also provided to assist the efficient operation of the facility, including systems to establish customer membership and charge accounts, and to verify credit at check out. Also included is a system to project labor schedules based on sales history and to produce payroll information on a scheduled basis. The system is connected to a remote headquarters computer for facilitating the timely communication of information to the point where it is required. 
     An important technical advantage achieved with the invention is the integration of point of sale and warehouse processing functions to enable delivery of merchandise to customers in the shortest possible time. 
     Another technical advantage achieved with the invention is real time access to merchandise availability, price, warranty and delivery information at a single point of decision for the customer, and the ability to offer selections to the customer based on this information. 
     Another technical advantage achieved with the invention is a store process flow which minimizes the use of store personnel yet which maximizes the provision of information and selection opportunities to the customer, thereby improving the shopping experience.

Upon entry of the delivery method into the computer 18, the warehouse 204 through the processor 14 is immediately notified if delivery to one of the pick up areas 206, 208 is required. All items ordered by the customer, whether through one or more sales persons, are stored in a single transaction record pertaining to that customer. Because information concerning delivery from the warehouse 204 is obtained immediately upon selection of the merchandise by the customer on the merchandising display floor 202, the merchandise can be transported to the pick up area 206 or 208 very quickly, typically prior to check out by the customer. 
     The pen-based sales transaction computers 18 may be used to refer to item data to show a description, item price, frequent purchaser point value, reduced price with points (if applicable), unit of measure, extended warranties available and stock availability. The pen-based sales transaction computers 18 further may be used to look up membership information, such as membership number, name, address, telephone number, accumulated frequent shopper points, credit availability, and receipt of advertising mailings indicator. Additional detail concerning the sales transaction process is set forth below. 
     Warehouse Distribution System 
     There is a two-way interface between the DCS application residing on the AS/400 processor 14 in the warehouse 204, and the POS controller 12. The POS controller 12 relies on the DCS application to provide accurate information of sale inventory. The DCS relies on the controller 12 to provide particular order information. Every time a customer places an order, a pen-based sales transaction computer 18 order interface is triggered to pass that order information along to the DCS system. The computer 18 interface sends the DCS customer pick up orders, delayed customer pick up orders, home delivery orders, installation orders and UPS delivery orders. The processing of orders is code-file driven, or directed by using an order/command function. Order picking can be done in an interactive fashion through the use of RF terminals such as scanner 44. Warehouse personnel can perform single order picking, batch or wave picking where many orders are picked simultaneously and sorted at a staging area (not shown). When an order is received from the computer 18 interface for immediate customer pick up at the customer service desk in the internal pick-up zone 206 or the pick-up loading zone 208, the order is released automatically and the inventory for the order is allocated from the warehouse 204. A pick will be generated and presented to a warehouse picker employee based on the picker&#39;s profile. The sequencing of picks are based on the order type, with customer pick-ups having the highest priority. Within the customer pick-up order type, the picks are sequenced by first-in, first-out (FIFO). Once the picker selects an item for picking, a customer pick-up label with the customer&#39;s name and order number is automatically generated on the portable printer of the picker&#39;s scanner 44. After the item is picked and labeled, it is placed on a conveyor (not shown) where it is diverted to an appropriate destination location, 206, 208. 
     Final Check Out 
     After ordering merchandise and services in merchandise display floor 202, the customer proceeds to the final check-out area 234. Check-out personnel operate the POS check-out registers 16 to perform customer check-out functions. The customer&#39;s membership number from the card 66 is entered into the register 16. The existing sales order transaction record is displayed on the screen of the register 16. The check-out cashier (not shown) is then able to review the order with the customer, add to the sale any additional items requested, or to void any unwanted items. The cashier is able to total the sale and accept cash, checks, gift certificates, credit cards, traveler&#39;s checks, store charge cards, and coupons as valid tenders. The customer is further able to purchase items with previously accumulated frequent shopper points, as indicated on the screen of the register 16. Credit authorization and data capture functions are performed by communication over the leased line 62 between the store 200 and the remote credit processing facility. Requests for credit authorization from the register 16 are authorized by the remote credit processing facility, through the POS controller 12. The register 16 receives the authorization status and pertinent information which is stored in the transaction log for further processing. Exception transaction data is forwarded off-line from the check-out register 16 to the credit processing facility. Backup copies of each day&#39;s data capture file are maintained in the register 16. The checkout register 16 is able to access item data from the controller 12 including item description, price, point value, reduced price with points, unit of measure, extended warranties available and stock availability. Membership information, including membership number and the customer&#39;s name and address, telephone number, accumulated points and the like are also available at the register 16. 
     A terminal (not shown) connected to the main store processor 14 is located in the departure area 236 of the store 200 to allow customers to change their delivery method after the customer has left the merchandise display floor 202. Also, sales personnel at the pick up area 206 are able to access the main store processor 14 directly to change the delivery/pick up method. 
     Upon check-out at the register 16, members are logged out of the store and are no longer eligible for the prize give-away lottery. If a customer leaves the store without being checked out at the register 16, after a period of time the system 10 will automatically log the customer out and they are no longer eligible for the prize give-away lottery. 
     Operation of the system 10 will now be described with reference to FIGS. 3 and 4. FIGS. 3a-3c are flow charts illustrating logic for implementing the selection, order and delivery functions of the retail store 200. FIGS. 4a-4c illustrate screen displays generated by the sales transaction computers 18 in performing the selection, order and delivery functions. 
     In step 300 (FIG. 3) a customer enters the store 200. In step 302 a determination is made whether the customer has a membership card to be presented for admission to the store. If the customer does not have a membership card, the customer is sent to the membership registration area according to step 304. If the customer is not a member according to step 306, the relevant membership information is taken in step 308 and the customer is issued a card in step 310. If the customer is a member in step 306 and the customer is not a visitor in step 312, the relevant membership information is similarly taken in step 308 and the customer is issued a card in step 310. If the customer is a member in step 306 and is a visitor in step 312, the relevant visitor information is taken in step 314 and the customer is issued a visitor&#39;s card in step 316. The foregoing membership registration steps are later described in greater detail with reference to FIGS. 7 and 8. 
     In step 318, the customer&#39;s membership card is scanned and the customer&#39;s membership information is stored in an in-store membership file. It is understood that the customer then proceeds to the entry tunnel 218 and may select merchandise for purchase. 
     In step 320, the operator of a pen-based sales transaction computer 18 scans the customer&#39;s membership card in order to initiate a potential transaction. While not shown, the display screen of the computer 18 prompts the operator to enter the member number directly, or scan the member card to receive the member number. In step 322, if the membership information input to the computer 18 is not stored in the in-store membership file, or if the number is not valid (such as for bad credit), in step 324 an error is indicated. If in step 322 it is determined that a valid member number has been entered, in step 326 the computer 18 displays an item entry screen used for building a sales transaction record for the customer. The item entry screen is illustrated in FIG. 4a and is designated by the reference numeral 400. The screen 400 indicates the customer name, member number and frequent shopper points earned at the top position of the screen. The screen 400 also includes several fields of information comprising the transaction record. The fields include item number; description; price and points; quantity; and price total. The fields also include a subtotal, tax and designation of frequent shopper points used. If a member has already created a transaction record by requesting the purchase of items previously during the day from another sales associate, that information is included in the transaction record and is displayed. The screen 400 includes Total, Modify and Exit commands in the lower left portion of the screen, the function of which are described below. 
     In the example of FIG. 4, the member has ordered Magnavox TV with a 12-month home warranty, and has requested the TV to be delivered. Also, the member has ordered a Sanyo car stereo which is to be installed. The stereo is being purchased using a price-plus-points option. 
     It is understood that the above product information comprising the transaction record was entered into the computer 18 using the light pen 18A to scan the product code labels 68 and to select various options on the screen 400. 
     If additional purchases are to be added to the transaction record, in step 328 the appropriate item number is entered into the computer 18 by the operator, such as by scanning the item label 68. In step 330, a determination is made whether the selected item of merchandise is stock. If the selected item is not in stock, in step 332 the computer 18 prompts the operator to suggest products comparable to the unavailable merchandise by displaying information on the screen of the computer. In step 334, a determination is made whether the customer desires information concerning products comparable to the unavailable merchandise. If the customer desires information concerning products comparable to the unavailable merchandise, the computer 18 in step 336 displays comparable product information. If the customer does not desire information concerning products comparable to the unavailable merchandise, execution proceeds directly to step 338. 
     In step 338, a determination is made whether the customer desires to purchase the comparable merchandise. If not, execution proceeds to step 340. If in step 320 the member does desire to purchase comparable merchandise, execution returns to step 328, the universal product code on the selected merchandise is scanned, and execution proceeds to step 330. If in step 330 it is determined that the selected merchandise is not in stock, execution again proceeds to step 332. If in step 330 it is determined that the selected merchandise is in stock, execution proceeds to step 340. 
     In step 340 (FIG. 3b), it is determined whether either a valid item number has been input to the computer 18 or the Modify function has been selected. If not, execution proceeds to step 342 where a determination is made whether the Exit function has been selected. If in step 342 it is determined that the Exit function has been selected, execution returns to step 320 without saving any information and the member number entry screen is displayed. If in step 342 it is determined that the Exit function has not been selected, execution proceeds to step 344. 
     In step 344, a determination is made whether the Total function has been selected. If not, execution returns to step 326. If in step 344 it is determined that the Total function has been selected, execution proceeds to step 346. In step 346, the transaction record is sent to the warehouse system residing on the processor 14 through the controller 12. The transaction record is used to create picking tickets for enabling warehouse location and retrieval of the merchandise. Reverse picking tickets are also created for items which have been deleted from the transaction. Further, if any item has already had a picking ticket created but the delivery method or information has changed, a reverse picking ticket with the old information is created and sent to the processor 14 followed by a picking ticket with the new information. The information comprising the transaction record is then saved and execution returns to step 320. 
     If in step 340 either a valid number has been input or the modify function has been selected on the computer 18, execution proceeds to step 348. In step 348, a pop-up Item entry information window 402 is displayed in the lower left hand corner of the item entry screen 400 of the computer 18, as shown in FIG. 4b. The item entry information window 402 includes the merchandise item code, description, regular price, point price, points needed for point price and item availability. The regular price and point price options have mutually exclusive selection buttons to the left of them, which enables the operator to select which price the member is to use. If the member does not have enough points available to use the points price, the points price button will be disabled. The sales price is displayed in the price field, once the operator has selected the price to be used and the quantity has been entered. The item entry information window 402 includes command designations for implementing override, discount, cancel and OK functions, of which the cancel and OK functions are described below. 
     In step 350, a determination is made whether the cancel function has been selected. If in step 350 it is determined that the cancel function has been selected, execution returns to step 326 where the item entry screen is displayed and any additions or changes made to the displayed items are discarded. If in step 350 it is determined that the cancel function has not been selected, execution proceeds to step 352. In step 352, a determination is made whether the OK function has been selected. If not, execution returns to step 348. If in step 352 it is determined that the OK function has been selected, execution proceeds to step 354. 
     In step 354, a determination is made whether the selected in-stock merchandise requires any additional products for operation. If so, in step 356 the computer 18 prompts the sales personnel with a display (not shown) listing additional products required for the operation of the selected merchandise. In step 358, a determination is made whether the customer desires to purchase the additional required products. If in step 358 it is determined that the customer desires to purchase the additional required products, the additional products are added to the transaction record in step 348, and execution proceeds to step 350. 
     If in step 354 it is determined that the selected in-stock merchandise does not require any additional products for operation, execution proceeds directly to step 360. Similarly, if in step 358 the customer does not desire to purchase the additional required products, execution proceeds directly to step 360. 
     In step 360, a determination is made whether there are any accessories that might be suggested for the selected in-stock merchandise. In step 362, the computer 18 displays suggested accessories for the selected merchandise. In step 364, a determination is made whether the customer desires to purchase any of the suggested accessories. If in step 364 it is determined that the customer desires to purchase some of the suggested accessories, the suggested accessories are added in step 348 to the transaction record, and execution proceeds to step 350. If in step 360 it is determined that there are no accessories that may be suggested for the selected in-stock merchandise, execution proceeds directly to step 366. Similarly, if in step 364 it is determined that the customer does not desire to purchase any of the suggested accessories, execution proceeds directly to step 366. 
     In step 366, the computer 18 displays the delivery options for the selected merchandise. A delivery method pop-up window 404 is displayed in the lower left hand corner of the Item Entry screen 400, as shown in FIG. 4c. The delivery method window 404 provides the operator with the plurality of delivery option selections including package pickup (P/U); dock; auto installation dock; delivery; UPS; delayed package pickup; and freight. Once the operator has selected a delivery method and entered the OK command, execution proceeds to step 368. 
     In step 368 (FIG. 3c), a determination is made whether either a package pickup, auto installation or dock delivery options has been selected. If one of the foregoing is selected, execution proceeds to step 370. In step 370, a warranty pop-up window (not shown) is displayed in the lower left hand corner of the item entry screen 400 which includes a plurality of warranty options. In step 371 a warranty selection is entered. To select a warranty option, the operator uses a select command (not shown) to the left of each of the options, and if a warranty is selected the warranty will be displayed on the item entry screen 400. Once the warranty option has been selected and the OK command is entered, or a decline command (not shown) is entered, execution proceeds to step 372. 
     In step 372, an installation option window (not shown) is displayed in the lower left hand corner of the item. To select an installation option the operator uses a select button (not shown) to the left of the desired option. If an installation option is selected, it will be displayed as a line item on the item entry screen 400. Once an installation item has been selected and an OK or decline command is entered, execution proceeds to step 373. 
     In step 373, an add-on item window (not shown) is displayed in the left hand corner of the item entry screen 400. The add-on item window prompts the operator to suggest add-on items of merchandise to the customer. Once the operator makes a selection from the items or declines by entering the appropriate command, execution returns to step 326 where the item entry screen 400 is displayed. 
     If in step 368 it is determined that the package pickup, auto installation or dock options have not been selected execution proceeds to step 374. In step 374, a determination is made whether the delivery option was selected from the delivery method window 404. If in step 374 it is determined that the delivery option has been selected from the delivery method window 404, execution proceeds to step 375. In step 375, a delivery information pop-up window 406 (FIG. 4d) is displayed in the lower left hand corner of the item entry screen 400. The delivery information window 406 displays the member name, address, telephone number, and alternate phone number as the default delivery information, which can be confirmed or changed by the operator by entering the appropriate commands. In step 376, the operator can strike through the displayed information and fill in information if different from the default information. Once the operator enters the OK command, execution proceeds to step 377. 
     In step 377, a delivery schedule pop-up window 408 (FIG. 4e) is displayed in the lower left hand corner of the item entry screen 400. The delivery schedule window 408 displays the first three available dates for delivery, as well as the cost for delivery. In step 378 the operator can select one of these dates and enter the customer&#39;s preferred day, with morning or afternoon delivery times. Entering the OK command will continue to return the next available set of possible delivery dates as long as a delivery date has not been selected for up to one month in the future. Once a date has been selected, entering OK saves the selected date, and execution returns to step 370 where the warranty pop-up window (not shown) is displayed in the lower left hand corner of the item entry screen 400. 
     If in step 374 it is determined that the delivery option has not been selected from the delivery method window 404, execution proceeds to step 379. In step 379, a determination is made whether the UPS shipping option has been selected from the delivery method window 404. If so, execution returns to step 375 and the delivery information window 406 is displayed. If in step 379 it is determined that the UPS option has not been selected, execution proceeds to step 380. 
     In step 380, a determination is made whether the delayed package pickup option has been selected from the delivery method window 404. If so, execution proceeds to step 382. In step 382, the delayed package pickup window 408 is displayed and execution proceeds to step 384. In step 384 the operator must enter a comment describing when the item will be picked up and execution returns to step 370. 
     If in step 380 it is determined that the delayed package pickup option has not been selected, execution proceeds to step 386. In step 386, a determination is made whether the freight option has been selected from the delivery method pop-up window 404. If so, execution proceeds to step 388. In step 388, the freight delivery pop-up window (not shown) is displayed in the lower left hand corner of the item entry screen 400. The freight window displays the member address, phone number, and alternate phone number as the default delivery information, and execution proceeds to step 390. In step 390, the operator can strike through the displayed information and fill in information which is different than the default delivery information. Further, the operator must enter the shipping charges and item weight. Once the operator enters the OK command, execution returns to step 370 with the display of the warranty pop-up window (not shown). 
     FIG. 5 illustrates an initial display screen 500 of the POS checkout registers 16. It is understood that once the customer has interfaced with operators of computers 18 to create a purchase transaction record including the delivery selections, the customer then proceeds to the check-out area 234 and pays for the items purchased by interaction with a register 16. The options available on the screen 500 for selection by the operator of the register 16 in handling customers include sale; no sale; nonsales; item lookup; member lookup; return; redeem credit memo; special order; and price protection refund. 
     The operator is able to access the customer&#39;s transaction record stored in the controller 12 or processor 14 by entering the member number. The member number is entered either by scanning the member card 66 or by keyed entry. The operator is then able to verify the purchases described in the transaction record, along with the various delivery, warranty and other options. The operator is able to edit the transaction record as required. The operator then accepts payment, as previously described. 
     FIG. 6 illustrates a flow diagram of a warehouse inventory management and distribution system 600 for the store 200. The system 600 includes as part of the main store processor 14 the AS/400 distribution center system (DCS) available from IBM. The system 600 tracks merchandise and directs work flow in the warehouse 204. 
     The system 600 relies on a relational database to track and control movable units of merchandise. The system uses the RF warehouse scanners 40 to provide work direction and to receive inputs from the scanning devices 44. The system 600 allows access to merchandise as soon as an operator releases the transaction record from the computer 18 through the controller 12, by generating a picking ticket in the warehouse 204. The system 600 provides processing in the form of receiving, picking and shipping and also tracking control by interaction with the JDA merchandising system residing in the merchandising system 56. The system 600 interfaces with the controller 12 and the registers 16 for real-time response to customer orders on the floor 202. A sales transaction computer order interface is triggered when a transaction record is furnished from the computers 18 to pass the order information to the DCS system. 
     In block 604, data regarding merchandise items arriving in the warehouse 204 are recorded in the processor 14 using the scan gun 46. The results are sent to the merchandising system 56. The processor 14 includes equipment for generating bar code labels to be affixed to the items. In block 606, items which are returns are serviced if they are in a nonsaleable condition. Returned items are entered into the processor 14 using the scan gun 46 and the result stored and sent to the merchandising system 56. 
     Items received in block 602 and saleable items returned in block 604 are put away as indicated in block 608. In block 608, the putaway function directs in real time the activities associated with transferring goods from one area in the distribution center to another. The putaway function interacts with a location map of the facility and determines the preferred and alternate locations for warehousing the item. For example, an environmentally protected item might be one that is contained in a secure cage, in a sprinkler area, or in a special storage for chemicals. One feature of the putaway function is its ability to override the preferred location with alternates. In block 810, order picking is accomplished in an interactive fashion through the use of the portable unit 44. Orders for items are picked for delivery to a specified location (such as pick-up area 206 or 208) utilizing a picking ticket generated by the processor 14 responsive to a transaction record request being received from the computers 18. The picking ticket may be an electronic display on the unit 44 or on a monitor (not shown), or may be printed in hard copy form. Single orders can be picked or employees can do batch or wave picking where many orders are picked simultaneously and sorted at a staging area. 
     In block 612, the processing of a customer pickup order begins when a picking ticket order is received for an immediate customer pickup at the pickup zone 206 or at the pickup loading dock 208. The picking ticket is presented to a picker based on the picker&#39;s responsibility profile. The sequence of handling picking tickets are based on the order type, with customer pickups having the highest priority. Picking tickets of a particular type are usually handled on a first in, first out (FIFO) basis. Once the picker selects an item for picking, a customer pickup label with the customer&#39;s name and order number is automatically generated to the picker&#39;s portable printer (not shown). After the item is picked and labeled, it is placed upon the conveyor (also not shown). As the item passes a scanner it is diverted to the appropriate location. 
     In block 814, all information necessary for the shipping interface, freight bills, manifest, and bills of lading are provided. This information is available for use by the merchandising system 56 as well as in a paper printout. 
     In block 816, cycle counting functions are provided to perform on demand cycle count inventories as well as analysis of cycle count results. Two forms of cycle count inventories are provided. The first is an on-demand cycle count inventory and the second cycle count inventory is based on a queue. The queue cycle count inventory directs a user to a location, item or unit that was determined to be in need of a cycle count. This information is furnished to the system 56. 
     In block 618, an inventory management function is provided which enables the system 56 to capture inventory adjustments based on the cycle count inventory, changed item status, and merchandise returned to vendors. In block 820, a management report function enables this information to be summarized and furnished to management in reports on a daily basis. 
     In block 622, an order processing function is provided which is used to create daily truckload schedules for shipping of merchandise from the store 200. The schedules are generated with the aid of a commercially-available decision support tool referred to as Trucks. Trucks is an automated vehicle routing and scheduling software tool that provides a systematic approach to solving transportation issues. Trucks takes into account the constraints on routing and scheduling operations. The order processing function receives information from the controller 12 concerning allocated merchandise and uses this information in processing the delivery. 
     FIGS. 7 and 8 refer to details of the store membership application function utilizing the new member processing system 22. In FIGS. 7a and 7b, flow charts illustrate logic for operating the new member processing system 22 using the PC 214. FIGS. 8a and 8b illustrate screen displays associated with the system 22. 
     In step 700, execution of the system is initiated. In step 702, the operator enters his operator I.D. and password on the PC 214. In step 704, a determination is made whether the operator is authorized to sign-on to the PC 214. If not, execution proceeds to step 706 and an error message is displayed on the PC 214. If in step 704 it is determined that the operator is authorized to sign-on, execution proceeds to step 708 where a membership application screen 800 (FIG. 8a) is displayed. 
     The membership application screen 800 provides the operator with eleven display options including display, add, change, and delete a member; adjust member points; replacement/lost member card; visitor member card; print membership card; new store charge account processing; review store charge applications; and commercial charge account processing. After the operator selects the desired option and presses enter, execution proceeds to step 712. 
     It is understood that the operator is granted authorization on an individual basis for each of the membership options. If the operator is authorized to access the membership option selected, the next screen for the selected membership option is displayed. If the operator is not authorized to access the selected membership option, an error message will be displayed at the bottom of the membership application screen indicating that the operator is not authorized to access that particular membership option. Consequently, the operator will only be able access the membership options that are authorized to him. 
     In step 712, a determination is made whether the operator has selected the &#34;display a member&#34; option. If so, in step 714, the operator is prompted to enter either the member name or the member number. Upon entering either the member name or the member number, execution proceeds to step 716. In step 716, a member screen 802 (FIG. 8b) is displayed. The member screen 802 contains the member name, address and telephone number in the upper left hand corner of the screen, and the member number and total frequent shopper point value in the upper right hand corner of the screen. The member screen 802 also contains information regarding whether the member has a store charge account, a commercial charge account, the member status code indicating whether the customer is a regular store member (M), a store charge member (T), a visiting member (V), or a commercial charge customer (C). At the bottom of the screen 802 are displayed a number of function keys including an F2 key, or change key, which can enable the operator to enter the change member information option; an F9 key, or print card(s) key, which enables the &#34;print a member card&#34; option; an F10 key, or print screen key, which can enable the printing of the member information contained on the member screen. All of the above information can be printed using a laser printer (not shown) that is attached to the PC 214. An F3 key, or quit key, exits the member screen 802. 
     If in step 712 it is determined that the operator does not want the &#34;display a member&#34; option, in step 718, a determination is made whether the operator has selected an &#34;add a member&#34; option. If so, in step 720, an add-a-member screen (not shown) is displayed. The following information must be added to process a new member: the member number, last name, first name, address, and country. Further, actuation of the F2 key, or new charge key, enables a new store charge account processing function. If in step 718 it is determined that the operator does not wish the add a member option, execution proceeds to step 722. 
     In step 722, a determination is made whether the operator has selected the &#34;change a member&#34; option from the membership application screen 800. If so, in step 724 the operator is prompted to enter either the member name or the member number. Upon entry of either the member name or the member number, execution proceeds to step 726. In step 726, the &#34;change a member&#34; screen is displayed to enable the operator to change the following data: the member last name, first name, address, phone number, status and negative check status. The F3 key, or quit key, issued to exit out of the change a member option. If in step 722 it is determined that the operator has not selected the &#34;change a member&#34; option, execution proceeds to step 728. 
     In step 728, a determination is made whether the delete a member option has been selected. If so, in step 730 the operator is prompted to enter either the member name or the member number. Upon entering either the member number or the member name, execution proceeds to step 732. In step 732, the delete a member screen is displayed and the operator has the ability to delete the member from the membership file by entering &#34;D&#34; in the appropriate field on the &#34;delete a member&#34; screen, and then actuating an &#34;enter&#34; command. An &#34;escape&#34; command exits out of the &#34;delete a member&#34; option and execution returns to step 708. If in step 728 it is determined the operator has not selected the &#34;delete a member&#34; option, then execution proceeds to step 734. 
     In step 734, a determination is made whether the operator has selected the &#34;adjust member points&#34; option. If so, in step 736 the operator is prompted to enter the member name or the member number. Upon entering either the member name or the member number, execution proceeds to step 738. In step 738, the &#34;adjust member points&#34; screen is displayed and a member&#39;s points can be adjusted. To adjust a member&#39;s points, the operator enters a &#34;+&#34; or &#34;-&#34; in the first position in the data field and then enters the number of points to be added or subtracted from the total number of points. The escape command exits out of the &#34;adjust member points&#34; option and execution returns to step 708. If in step 734 it is determined the operator has not selected the adjust member points option, execution proceeds to step 740. 
     In step 740 (FIG. 7b), a determination is made whether the operator has selected the &#34;replacement/lost member card&#34; option. If so, in step 742 the operator is prompted to enter the member name or the member number. Upon entering either the member name or the member number, execution proceeds to step 744. In step 744, the replacement/lost member card screen is displayed. This display allows the operator to replace a member&#39;s card that has been lost, stolen or should be closed. From the replacement/lost member card screen, the operator can modify the member information on the screen, including providing the member a new member number, change of the member name, address, business phone number and number of additional cards, if any. The operator then can actuate the escape command to return to step 708. If in step 740 it is determined the operator has not selected the &#34;replacement/lost member card&#34; option, execution proceeds to step 746. 
     In step 746, a determination is made whether the operator has selected the &#34;visitor member card&#34; option. If so, in step 748 the visitor member card screen is displayed. The visitor member card option allows a visiting member to open a membership at an alternate store 200. However, the frequent shopper points that are earned at a visiting store are not accumulated under the visiting store member number, and are added to the visitor&#39;s total at his home store. Store personnel are responsible for calling or sending the visitor member information to the member&#39;s home store. The point total is adjusted at the home store as previously described in step 734. The information required for a visitor member card is analogous to the information required in step 718 for the add a member option. The escape command returns the operator to step 708. If in step 746 it is determined that the operator has not selected the visitor member card card option, execution proceeds to step 750. 
     In step 750, a determination is made whether the &#34;print membership card&#34; option has been selected. If so, in step 752, the operator is prompted to enter the member name or the member number. Upon entering either the member name or the member number, execution proceeds to step 754. In step 754, the print member card screen is displayed. The print member card screen allows the operator to print additional membership cards for family members or for members who need temporary cards.
