User's Guide to Batch Processing of OpScan 100 Scan Sheets. (1972)

Batch processing of OpScan 100 Scan Tapes is performed on the 690 System in INS ComSys 1 and 2. Described are the operating procedures, formats handled, and the messages printed.

USER'S GUIDE TO BATCH PROCESSING OF OPSCAN 100 SCAN SHEETS John Yu 4 .Batch processing of OpScan 100 sheets starts with receipt of mark reader scannable sheets from scho &ls by mail or courier service as defined in EMS ComSys 1 and 2 (TN 5-72-03). The sheets are then scanned by the OpScan 100 Mark Reader and images are produced onto an OpScan Scan Tape., Throughout this guide-the term scan sheet is used to refer to tape images rather than the physical sheets them. selves. OPSN, the 690 IMS ComSys 1 and 2 input processor interprets the tape images and produces card image records onto another tape. The card image records are then in a form that can be transmitted to IMS resident programs at UCLA via RJS. This guide describes the operation of OPSN, its alternate input mode (teletype), the interpretation of error messages produced by OPSN, the listing of the OpScan 100 Scan Tape and the card image tape, and the types of OpScan 100 sheets that can be processed. OPSN PROGRAM DESCRIPTION The current version of OPSN can handle six types of sheets designed for the OpScan 100 (see Appendix for the format of the sheets and the manner in which each type of is recognized). There are two modes of inputs: teletype input and tape input. Input tape must be created with LOW (556 BPI) density and EVEN parity. The input tape must be on unit 2 with no write ring, and there must be an end-of-file (EOF) at the end of all logical records: a logical record being the image of a sheet. Teletype input can be used to delete or add new students to the IMS data base. There are two modes of outputs: printer output and magnetic tape output. The printer output is a log of classes processed and error messages. These error messages indicate errors detected'by OPSN. Magnetic tape output is in HIGH (800 BPI) density.and ODD parity. It must be mounted on unit 3 with a write ring. One logical record is one card-image of packedXS40 characters. Inputsequence After OPSN is loaded in the 690 System, the operator is requested 7 to provide the header informatidn-tirrig,the teletype. Header information consists of a six-digit date, fourcharacter -tape identifier and a four-digit time-of-day. It is used to identify the magnetic tapoutput and the printer output. 21 Header Information. OPSN types out DATE= and waits for operator response. Response'must be a six-digit date, two digitsfor each of month, day, year in that order. No carriage return is needed. OPSN then types TAPE ID=. Response must be at least one but leith than five characters, no carriage return is needed for four characters. For less than four characters, the tape identifier is right-justified. Then OPSN types TIME=, response is optional, maximum being four numeric digits. No carriage return is needed for four digits, output is leftjustified. Teletype Input Option. After the header information is given, OPSN types out TELETYPE INPUT? If operator response is N, teletype input section will be skipped and OPSN starts the tape input section. If teletype input is desired, operator response must be Y, this causes a
