CICS reserved-word table

COBOL provides an alternate reserved-word table (IGYCCICS) for CICS® application programs. If you use the compiler option WORD(CICS), COBOL words that are not supported under CICS are flagged with an error message.

In addition to the COBOL words restricted by the IBM-supplied default reserved-word table, the IBM-supplied CICS reserved-word table restricts the following COBOL words:

  • CLOSE
  • DELETE3
  • Start of changeFACTORY End of change
  • FD
  • FILE1
  • FILE-CONTROL1
  • INPUT-OUTPUT1
  • Start of changeINVOKE End of change
  • I-O-CONTROL
  • MERGE
  • Start of changeMETHOD End of change
  • Start of changeOBJECT End of change
  • OPEN
  • READ
  • RERUN
  • REWRITE
  • SD1, 2
  • Start of changeSELF End of change
  • START
  • Start of changeSUPER End of change
  • WRITE
Notes:
  1. If you intend to use the SORT statement under CICS (COBOL supports an interface for the SORT statement under CICS), you must change the CICS reserved-word table to remove the words from the list of words marked as restricted.
  2. Start of changeThe SORT keyword is not restricted, but the SD keyword is. This allows you to use the format 2 (table) sort statement but not the format 1 (file) sort statement. End of change
  3. If you restrict the DELETE keyword, you may still use the DELETE function of BASIS processing.
