APPENDIX1.4 Appendix D. Reserved Words

This list identifies all reserved words in the COBOL for OS/390 & VM, COBOL Set for AIX, and VisualAge COBOL products. It also identifies words that are reserved in the COBOL 85 Standard (which are not reserved in the IBM COBOL products), and words reserved for future development.

Note: You can change which reserved word table is used by using the WORD compiler option. For details, on how to specify an alternate reserved word table, see the IBM COBOL Programming Guide for your platform.
