ivChapter 1. The 3730 Distributed Office Communication System
The IBM 3730 Distributed Office Communication System (see Frontispiece) is
designed to help simplify the production of office correspondence and other businessdocuments.
With the 3730 system your organization can:•Type documents rapidly at a screen.
•
Make changes easily when a document is to be revised.
•
Take advantage of keyboard functions that automate many of the tasks usually
carried out manually.
•
Let the system format documents automatically.
•
Store frequently-used text (sentences, paragraphs, and letters) for later recall as
often as necessary.
•
Have less repetitive typing.
•
Use time more efficiently by letting the system print documents while others arebeing typed.
•
Automate various office procedures, for example, mail logs.
•
Have clerical and administrative staff use few keystrokes to create unique
documents from prestored text.
The 3730 Distributed Office Communication System consists of IBM 3732 Text
Display Stations, IBM 3736 Printers, and an IBM 3791 Controller. These units areshown in Figure 1-1 and are described in Chapter 2.

Chapter 1. The 3730 Distributed Office Communication System

The Size of a 3730
SystemThe size and arrangement of a 3730 system can be matched to the needs of yourorganization. The smallest system must have a 3791 Controller, a 3732 Text Display
Station with a keyboard, and either the line printer feature of the 3791 Controller or a3736 Printer. The largest single system can have a 3791 Controller and up to a
combined total of thirty-one 3732 Text Display Stations with keyboards and 3736
Printers (or a maximum of thirty if the controller is fitted with a line printer feature).
A number of factors influence the performance of the system, for example, thenumber of display stations being used at one time and the type of work being done atthem.
The display stations and printers can be up to 609 meters (2,000 feet) from the3791 Controller.

Extending the
Functions of the3730 System

On its own, the 3730 system offers comprehensive text-processing functions forcreating, editing, storing, printing, and archiving documents. The functions of the3730 system can be extended by the use of application programs to suit your needs
and by connecting the system to the computer of a host system. Programs can be
written to run in the 3730 system or in a host computer.

Application Programsfor the 3730 System

Using 3730 programs, the 3730 system can, without connection to a host computer,carry out a wide range of more specialized applications such as:•
Providing secretarial aids, including keeping executives' diaries of appointments,
and prompting when replies to correspondence are due.
•Automating the logs of incoming and outgoing mail.
•Supplying variable information for use in 3730 documents.
Programs for the 3730 system are prepared at a computer and then eithertransmitted to a connected 3730 system or transferred to diskettes, which can beloaded into any suitable 3730 system.

Communicating with a
Host Computer

If the 3730 system is connected to a host computer, 3730 system functions can beextended by application programming to allow:•
Documents sent from a 3730 system to be stored at the host system.
•
Documents stored at the host system to be sent to a 3730 system.
•
Documents to be distributed among the 3730 systems connected to the same
host computer.
•
Information stored in the host system to be used so that, for example, centrally
held details may be included in locally generated correspondence and otherdocuments.
See Chapter 5 for further details of programming for the 3730 system and ofcommunication with a host computer.

Streamlining
Document
Production

Office costs are a large percentage of the expense of running most businesses.
Increasing the speed with which documents are produced and reducing the number ofretyped documents can greatly improve office efficiency.
Take, for example, the production of a monthly report. It probably contains parts
that hardly change from month to month, and parts that are new each month.
With the 3730 system, the first of these reports is produced by the following steps:
I. The originator writes or dictates a draft.
2. The operator types the draft at a 3732 Text Display Station, without
interruptions for paper-handling and without worrying about mistakes. (Mistakes
are easily corrected.)

Chapter 1. The 3730 Distributed Office Communication System

1-3

The keyboard of the display station has keys (for example, to underscore awhole word) that automate many of the tasks a typist does manually at a
typewriter.
In addition, the 3730 system has features that make it easy to produce properlyformatted text; for example, the operator can type a heading and/or footing once,
and the system can print it subsequently on every page of a document.
3. When the operator has finished the draft, a copy can be printed while theoperator types another document.
4. The originator corrects and amends the printed Clraft as necessary.
5. The operator types only the corrections and amendments; the unchanged text
remains in the system.
6. The final version is then printed at a local 3736 Printer or at another 3736
Printer that is nearer to the recipient.
When the next month's report is due, the operator retrieves the previous month's
report and replaces any changed information. The operator also types the new text toassemble a complete unique document. Because the operator has typed only the newtext, only the changes need to be proofread. The typing and editing of documents aredescribed in Chapter 3.
Besides speeding the typing, editing, printing, a~d updating of documents that are
typed at the keyboard, the 3730 system can generate complete documents frompatterns. These consist of prestored pieces of text and specifications for inserting one
or more of the following:• Other prestored text.
• Information typed by the operator.
• Information retrieved from 3730 system storage.
• Information obtained from the host computer.
• Information generated by application programs.
With few keystrokes, an operator can assemble a personalized document containing
up-to-date information. The use of prestored text can save time and effort and is ofparticular benefit when accuracy and presentation are important.
Patterns and the production of automated text are described in Chapter 4.

Aids for the Operator

The 3730 system can be used by typing, secretarial, and clerical staff with little
additional training. The keyboard of the 3732 Text Display Station is similar to thatof a typewriter. The screen displays prompts _and messages when necessary and, incertain circumstances, highlights pieces of text and errors to assist the operator.
Changes appear on the screen as they are made.
For new operators, a training handbook contains instructions for the 3730 system.
After using this handbook, operators should be able to use the system straight away.
For all-operators, two other aids are available:• Pressing the HELP key of the display-station keyboard causes the screen todisplay step-by-step details of how to use the system.
• A quick-reference booklet, readily to hand in a compartment in the keyboard,assists the operator who may have problems.

Safeguarding
Information

The 3730 system protects documents and information in the following ways:• The 3791 Controller and 3732 Text Display Stations can be fitted with keylocks
to prevent unauthorized use.
• Before operators can use a display station, they must each type their operator
number and password, which the system checks.

Concurrent
Operations of 3730
and 3790 Systems

Each operator has a 'profile' that defines which functions are available to that
operator. A profile may specify, for example, whether an operator is allowed touse documents from another operator's store.
When the operator stores a document, it must always be given a document
name, which must be specified when the document is retrieved. It may also begiven a get code and a delete code; if a document has a get code, this must be
specified before the document can be printed or displayed; if it has a delete
code, this must be specified before the document can be deleted or overwritten.
Copies of important documents can be sent to the host computer, or recorded on
diskettes, which can then be stored in a different location.

The 3730 system can operate concurrently with the IBM 3790 Communication Systemusing the same 3791 Controller. In such a system, terminals of the 3730 system dotext-processing work and terminals of the 3790 Communication System do dataprocessing work. For more details of concurrent 3730-3790 operations, see Chapter 6.

Commands

The display-station operator uses two types of commands: immediate commands and text
commands. Immediate commands (used, for example, to set a new width) take effectstraight away. Text com.mands (used, for example, to number successive pages) areentered as part of the document; they take effect only when the document is formatted
or printed.
Commands consist of easy-to-remember characters, for example, 'wd' for setting awidth, 'pn' for page numbering. The operator can either type the whole command or,with immediate commands, can be prompted for each part of the command.
Using such commands the operator can, for example:• Define a new line width and page depth.
• Set normal, centering, and decimal tab-stops.
• Cause text to be automatically centered.
• Define a heading and footing once at the beginning of a document, and have it
automatically printed on every page.
• Find a particular page, word, or phrase.
• Change the first or every occurrence of a group of characters to something else.
• Define how documents are to be printed.

Document Storage

There are three types of storage in the 3730 system:• Working store.
• Permanent store.
• Archival store.
Working store holds a document while the operator is working on it, that is,typing, displaying, or editing it.
Permanent store is where the operator stores the document if it is to be later
displayed, edited, or printed. A document remains in permanent store until deleted.
Archival store is where documents may be held when they are not frequently used
but must be retained. It can also be used for storing backup copies of documents held inpermanent store. Documents can be archived by being copied onto diskettes, or being
copied and sent to a host computer. When the archived document is required, it is copied
back into permanent store.

Typing a Document·
Adjust ModeAs their typing approaches the end of a line, typists usually slow down (although they
may not be aware of this) to consider the best· place to start'a new line and whether ahyphen is required. The 3730 system removes the need for line-ending decisions
through adjust mode.
Adjust mode is normally used whenever text, that is, sentences and paragraphs, isbeing typed. When text is in adjust mode, the screen automatically starts a new line
when typing reaches the right margin. If a word does not fit on the line, the word isautomatically placed on the next line. The operator does not need to look up to
check line endings or to decide when to start a new line, and therefore can maintainfull typing speed.
When typing reaches the last text line of the screen, a tone sounds to warn theoperator that the screen is almost full. The operator then presses the ENTER key andcontinues on a fresh screen.

No-Adjust Mode

No-adjust mode is normally used when tables and other work with a special layout
are being typed.
When the text is in no-adjust mode, the system does not automatically start newlines. A tone sounds when the typing is five positions from the right margin but theoperator must choose the ends of lines by pressing the New Line (RETURN) key.
The system leaves text in no-adjust mode exactly as it was entered.

3-23730 System Introduction

The operator can change from adjust mode to no-adjust mode and back as manytimes as are necessary in the same document by pressing the appropriate function
keys.

Correcting a
Document While
TypingA typist usually notices most typing errors as soon as they are made. To correct such
errors, the display-station operator presses the Backspace Delete (BACKSPACE) key
to delete the incorrect character(s). The operator does not need to erase from multiple
copies or spend time painting out a mistake on paper.
If an operator is typing from dictation (either from shorthand or audio equipment)
and the originator unexpectedly gives an instruction to insert text in a section thathas already been typed, the operator just returns to the appropriate screen, presses
the Block Insert (BLK INS) key and types the insertion. The insertion can be of any
size and can contain text in both adjust and no-adjust modes.

Indenting Text

Text can be indented in both adjust and no-adjust modes by the operator setting atemporary left margin. For text in adjust mode, the system then automatically starts
each line at the temporary left margin. In no-adjust mode, the system starts each newline at the temporary left margin when the operator presses the New Line (RETURN)
key.

Typing Tables

Tables, such as for accounts and sales statistics, are normally typed in no-adjust modeso that the column layout is preserved by the system exactly as it was entered.
To make the typing of tables simple and speedy, the 3730 system has three types oftab stop: ordinary, centering, and decimal. Furthermore, the keyboard has a dual purpose
key that assists the operator in typing the table either line-by-line, or column-by-column.

Editing a Document

Editing or updating a document on the display-station screen is quick and simple.
Keys and commands are provided for displaying the top or bottom of a document,each screen, or a specified page or sequence of characters. The screen enables theoperator to delete, move, copy, and insert text in an existing document or evenchange the width. The operator then adjusts the document by either pressing the
ADJST key or entering an Adjust-with-Hyphenation command to produce a final
document, which is correctly formatted despite all the changes.
A Display (DISP) key assists the operator to edit a document. This key controls
the displaying of symbols that represent spaces, new lines, and tabs. Use of this key
shows exactly how the document was originally typed so that operators can update
work they did not themselves originally type.

Deleting Text

Function keys allow the operator to delete each of the following: a character, a word,a line, a sentence, and a block of text. A block can be of any size.

Inserting Text

When a screen of text is displayed, two empty lines remain at the bottom. If the text
is in adjust mode and the operator inserts some characters, words following theinsertion move down to the following line. This effect may continue down the screen
from line to line until the screen is full. If the text is in no-adjust mode, however, theoperator can insert words until only a particular line is full.
To insert large pieces of text in both adjust mode and no-adjust mode, the operator
uses the Block Insert (BLK INS) key. When this key is pressed, the screen displays
the last two lines of text before the insertion. The operator can then type theinsertion, which can be of any size.
Chapter 3. Typing and Editing Documents

3-3Moving and Copying
Text

The 3730 system assists the operator both to move a block of text from one place toanother in the same document, and to copy a block of text so that it appears twice(or more times if necessary) in the same document.
The operator simply indicates the beginning and end of the block, then chooses the
position where it is to appear. The system highlights the block before the change ismade so that the operator can confirm the action.

Changing Text

Two immediate commands are particularly useful during editing: Change First andChange All. The Change First command causes the text to be searched from where
the cursor is positioned and changes the first occurrence of a specified sequence ofcharacters to another specified sequence. Similarly, the Change All command replaces
every occurrence of a specified sequence of characters by another specified sequence.

Dividing a Document
into Pages

As we have seen, the 3730 system solves, through adjust mode, the problems of lineending decisions. It also removes the need for page-ending decisions. As their typing
approaches the end of a page, typists usually slow down to consider where to start thenext page and to avoid making a mistake that could necessitate retyping the whole page.
With the 3730 system the operator types the whole document, however long, anddoes not worry about ending pages. When the document is finished, the operator
presses a key (the ADJST key) that divides the document into pages of the chosen
depth. The operator can then look through the document on the screen to check thatthe page-endings are suitable. The 3730 system automatically avoids separating asingle line of text from the rest of its paragraph but, if the paging is not satisfactory,
the operator can type a comrnand to force a page to end in another place.
If the document is to be printed with a justified right margin, the operator may
decide to use the Adjust-with-Hyphenation command instead of the ADJST key.
Adjust-with-Hyphenation can reduce the rivers of white space that sometimes appear
in documents printed with a justified right margin.
The Adjust-with-Hyphenation command divides the document into pages after
highlighting each word that could be hyphenated. For each of these words, theoperator either chooses a point at which the system is to insert a hyphen and end theline, or leaves the whole word at the beginning of the next line.

Printing a Document

Typing and printing are done separately in the 3730 system. The operator types andedits the document on the screen but a copy is printed only when required.
Two ways are available for requesting the system to print a document:• The operator can type one of three print commands, which specify whether the
document is to be printed exactly as displayed, with a ragged right margin, orwith a justified right margin. Figure 3-2 shows results of the three commands.
• The operator can press the PRINT key of the display-station keyboard. The
document will be printed by a printer and in a format both of which have beenpredefined for that operator.
When a print request is made, the document is placed in a queue. The printing of
documents held in queues is controlled by a supervisory operator. When all the
documents in a queue have been printed, the queue may remain active so that thenext request causes printing to resume.
By using the appropriate text command, the display-station operator can specify
spacing of I, 1.5, 2, or 3 lines for a document to be printed by the 3736 Printer, andspacing of l, 2, or 3 lines for a document printed on the line printer feature of the3791 Controller.

Operations

3730 System Introduction

The day-to-day running of the system is controlled by supervisory operators who areresponsible for operations such as:• Starting up and closing down the system.
• Controlling operator access to the system.
• Controlling printing and archiving operations.
• Providing a common layout (line width, page depth, and tab-stop settings) that is
automatically in force when the operators start work.
• Controlling the amount of system storage each operator can use for documents.
• Taking corrective action should problems arise.
Depending on the size of the system, the different departments who may use it,
and how it is physically arrang'<d, you may wish to select one or more supervisory
operators.

Chapter 4. Producing Automated Text
A large proportion of the correspondence produced by many businesses consists ofthe same sentences and paragraphs used again and again.
Using the automated-text facilities of the 3730 system optimizes accuracy andcontrol by centralizing the source of text, and minimizes the amount of new
information to be provided when a specific document is to be produced.
Identifying which text your organization uses repeatedly and storing it in thesystem once, can improve document accuracy and uniformity, and can speed
production for all display-station operators. Once the original text has been stored,
any number of operators can use it at any time.
Those who request prestored text do not have to be skilled typists. They can be, forexample, clerks or administrators who make short inserts in the prestored text.
The 3730-system automated-text functions handle two types of prestored material:• Pieces of text.
•
Patterns.

Chapter 4. Producing Automated Text

Producing Documentsfrom Prestored Piecesof Text

Prestored text (l) can save your organization time spent on documents that consist of
frequently used pieces of text, and (2) can help to ensure that those documents areaccurate, and that they will appear unique to their recipients.
Pieces of frequently used text, containing indications of where any insertions are required,
need only be stored once in the 3730 system's permanent store. Subsequently, theoriginator of an important document (say, a contract) needs only to list the names of theprestored pieces of text and write any insertions. A display-station operator can thenassemble the complete document by:
I. Getting the pieces of text in sequence from permanent store.
2. Finding the points at which the insertions are to be made, either by inspecting
the screen or by using a Find command.
3. Typing the insertions.
Figure 4-1 shows how the separately stored parts of a contract are used to produce
a unique personalized document.
A long document can be accurately produced from very few keystrokes. It is often
convenient to produce a draft for the originator to mark as negotiations take place
and terms are settled. The draft can be quickly revised at a display station using thesystem's normal editing facilities. Parts of the document that must not be alteredunder any circumstances can be protected from editing.

Producing
Documents from
Patterns

A pattern is a prestored document that is defined once and subsequently used as often
as required. It consists typically of text and references to sources of information. Thereis one such reference at every point in the text where variable information, such as a name,is to be inserted. Patterns are used when the same document, for example, an orderacknowledgment, is used on many occasions.

Defining a Pattern

Like other documents, patterns are created at a 3732 display station. In addition totyping the text, the operator enters special commands at each point where variable
information is to be inserted. These commands, provided by IBM, indicate
information is to be obtained from:•The keyboard of a display station.
•
A document stored in the system.
•
A file stored in the system.
•
A program.
When information is to be obtained from the keyboard, the operator who designs
the pattern may also define the prompts (for example 'Type recipient's name'), which
will appear on the screen when the pattern is used.
When defining the pattern, the operator also specifies how documents obtained
from the pattern are to be printed (for example, by which print command and thenumber of copies).

Using a Pattern

To create a unique document from a pattern, an operator simply requests the patternby name and replies to the prompts, if any, which are then displayed. The 3730
system obtains the variable information and merges it with the text of the pattern toproduce a properly formatted document.
Figure 4-2 shows an example of a pattern, the information that appears on thescreen, and the final Jetter.
IBM provides a facility to extract names and addresses from a list stored in thesystem. The names and addresses are accessed one after another so that, for example,
a pattern can be personalized automatically for everyone on the list.

Preprinted Forms

4-63730 System Introduction

A pattern can be used when personalized information is to be printed in specified
places on a preprinted form.
The source of each piece of information that appears on the form is predefined in
the same way as the insertions in patterns. The source can be the keyboard, a stored
document, a file, or a program. The position of each piece of information is alsopredefined, and so are the prompts (if any) that request information from the displaystation operator.
The display-station operator requests the pattern and supplies responses to any
prompts.
Figure 4-3 shows (1) an example of the information that an operator sees after
requesting a pattern and (2) the form that has been completed using the information
supplied from the keyboard and from files stored in the system.

Chapter 5. Extending the 3730-System Functions

The text-processing functions of a 3730 system can be extended by (1) application
programming and (2) connection to a host computer. Application programs may run ina 3730 system that is or is not connected to a host computer. Other application programs may run in a host computer.

Writing 3730
Programs

Writing programs for a 3730 system is similar to writing programs for an IBM 3790
Communication System. 3730-programs are written using 3730 and certain 3790 programming statements, which are assembled and processed on a computer such as thatof an IBM System/370, and are tested at the 3730 system. The programs can be stored
either in the 3791 Controller or on diskettes from which they can be loaded into thecontroller when required.
For further information on programming, see IBM 3730 Distributed OfficeCommunication System: System Description, GA33-3022.

Examples of 3730
Programs

Programs for the 3730 system can be written to support your organization's specificrequirements. The following examples show the use to which 3730 programs can beput:• Creating and updating local name/address and customer data files.
•
Accessing each of the addresses in a file and selecting recipients who satisfy certain
criteria for mass mail (see 'Selective Mass Mail' below).
•
Generating a personalized letter by searching files and carrying out calculations
when a clerk enters an inquiry from a customer.
•
Extracting details from files about the products that people have bought andincluding those details in a letter offering more of those products at a special
price.
• Carrying out validity checks on data that is to be included in a document. For
example, checking that the first figure is not greater than 10% of the second
figure.
• Triggering some action when a certain date arrives. For example, listing theevents in a diary for that date, or indicating that the reply to a previously sentletter is due, or automatically generating a reminder letter.
•
Logging outgoing mail.
• Keeping a log of incoming mail.

Selective Mass Mail

Mass mail normally consists of letters, possibly with some variable content, that aresent to a large number of addresses. IBM provides a facility to extract each address inturn from a file of addresses stored in the system. The addresses can be used, forexample, when the same letter is sent to many recipients. If the names and addresses
are to be selected according to certain criteria, programs that supply the logic forthese criteria are needed.
Figure 5-1 illustrates a letter addressed to customers whose files show they havefrequently used a particular service.

3730 System Introduction

Methods ofConnection to a
Host Computer

The 3791 Controller of a 3730 system can be connected directly, or via telephone lines,
to a host computer. The host computer can be any virtual-storage model of IBM
System/370, an IBM 3031, 3032, or 3033 Processor, or IBM 4300 Processor.
If the 3730 system is over 61 meters (200 feet) from the host computer, connection can
only be through a suitable communication line, using permanently connected or dial-up
lines and an IBM 3704 or 3705 Communications Controller.

Examples of HostRelated Programs

Application programs requiring a host computer can be developed to support yourorganization's specific requirements. Examples of these requirements are:•Sending documents to the host computer for archiving.
•
Sending documents from one 3730 system to any other attached 3730 systems by
way of the host computer.
• Real-time or batch update or inquiry of host-system data bases, for example,
Customer Information Control System/Virtual Storage (CICS/VS) or
Information Management System/Virtual Storage (IMS/VS) data bases.
•
Accessing and using data stored in the host system, to allow centrally held
information to be included in locally generated correspondence and otherdocuments.
• Creating a host-based central file of documents, with retrieval by search on
specified search terms. (The search terms associated with each document must be
specified when it is filed.)•
Sending documents to the host computer for preprocessing or conversion prior to
input to other text-based systems.

Programming
Support for HostRelated Programs
Programming Support
at the Host Computer

All the above examples of host-related applications require programs that control,
store, process, or redirect documents received at the host computer. These hostprograms must be provided by your organization.

Programming Support
at the 3730 System

The 3730 system provides a document transmission function that can send or receive
documents to or from a host computer. Host applications to communicate with thisfunction can be CICS/VS or IMS/VS transactions, or Virtual Telecommunications
Access Method (VT AM) or Telecommunications Access Method (TCAM) applications.
For example, straightforward archiving or retrieval can be accomplished without any
3730 programming.
The 3730 document transmission function can also be used as a basis for more
complex host-related applications.
With 3730 programming, systems may solicit and check their own data, (forexample, filing or distribution data) and may associate this data with a document
before transmitting both, by the document transmission function.
Several 3790 host-communication functions are available with the 3730 system, or
your organization can program communication applications independently of the
IBM-provided functions.
For further information on host connection and the IBM-provided documenttransmission function, see IBM 3730 Distributed Office Communication System:
System Description, GA33-3022.

A 3730 system and a 3790 system can be combined so that their respective textprocessing and data-processing terminals are attached to the same 3791 Controller.
It may have been difficult in the past to justify a dedicated text-processing systemor a dedicated data-processing system, but a combined 3730-3790 system can give thebenefits of both systems without the cost of two systems.
The 3730 terminals are:3732 Text Display Station
