2. Environment Description

The detail input file is a non-labeled, ungrouped, BCD tape file produced on card-to-tape equipment. On the input tape a 3-word record occupies the first portion of tape blocks 14 words long.

Only the 3-word record is to be brought into storage and processed, and the specification BLOCKSIZE 3 on the DETAILFILE FILE cards accomplishes this aim. Alternatively, BEGIN and BLOCKSIZE 14 might have been specified on the FILE card which would have enabled correct processing but allowed the full 14-word block to enter core.

E. Output Report Files

In this problem four output files are prepared for listing: CHECKFILE, BONDORDERFILE, PAYFILE, ERRORFILE.

1. The CHECKFILE

a) Data Description

The Data Description of CHECK records in the CHECKFILE specifies a 2-line check to be printed under carriage control on a 720 printer. A standard carriage control tape is assumed with Channel 1 associated with the first check line and Channel 2 four spaces away for the second line. The two check lines are grouped in one record, separated by a record mark (signalled by type RCDMRK) for printer control.

The CHECK records would be composed of:

  • Word 1 — carriage control character; 2 characters for MONTH; a dash; 2 characters for DAY
  • Word 2 — a dash; 2 characters for YEAR; 3 blanks
  • Word 3 — 6 blanks
  • Word 4 — 6 blanks
  • Word 5 — 6 blanks
  • Word 6 — 6 blanks
  • Word 7 — 3 blanks; first 3 characters of EMPLOYEE.NUMBER
  • Word 8 — last 3 characters of EMPLOYEE.NUMBER; record mark; carriage control character; first character of NAME
