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