05.05 OUTPUT FROM SYSTEM

A. Compiler

The CT Compiler output consists of:

  1. A list of the source program and error messages concerning the source program is written on the SYSOU tape. In addition, the programmer may obtain on SYSOU a listing of the object program generated by the Compiler. SYSOU must be a tape unit. Attaching the on-line printer as SYSOU will not work.
  2. Punch output is placed on SYSPP. SYSPP may be a tape for off-line punching or the on-line punch.
  3. Operator messages are written on-line printer. End-of-file marks are put on SYSOU and SYSPP as part of the reel switching operation and through the use of Basic Monitor Control Cards. The separation of decks from off-line punching must be accomplished by means of the deck identification punched in columns 73-77, and a card sequence number punched in columns 78-80. The deck identification comes from columns 8 through 12 of the $CMPLE card.

B. Loader

The CT Loader during the loading operation may write on SYSOU. No other output will occur except operator messages on the on-line printer.

C. Subroutine Files Updater

The Subroutine Files Updater produces new subroutine files on SYSUT2 and may produce a map of these subroutine files on SYSOU, and/or messages on the on-line printer.

D. File Maintenance

The CT File Maintenance produces a new BCD system master tape on SYSLB4, an input tape for the assembler on SYSUT4 and SYSUT3, and writes error messages on the on-line printer.

*NOTE The output written on SYSOU from the Compiler and Loader is grouped 5 lines per physical record with record marks after each of the first 4 lines. If a 720 printer is used to list the tape, the group switch must be set to 5.
