Enterprise COBOL 3

Most Enterprise COBOL 3 programs will compile without change under Enterprise COBOL 5 or 6.

The following programs, however, will need to be upgraded:
  • Programs that use words which are now reserved in Enterprise COBOL
  • Programs that contain the format 2 declarative syntax: USE...AFTER...LABEL PROCEDURE..., and the syntax: GO TO MORE-LABELS.

For details, see Upgrading programs from Enterprise COBOL 3.
