The command-line option "-Cv" (either on the command line or in the CBLFLAGS environment string) allows the ACUCOBOL-GT compiler to be compatible with IBM DOS/VS COBOL. In this mode, it accepts features of IBM DOS/VS COBOL that are not otherwise accepted by ACUCOBOL-GT.
This appendix provides information about the IBM DOS/VS COBOL features that the ACUCOBOL-GT compiler supports. Complete IBM DOS/VS COBOL compatibility is, unfortunately, not feasible. However, in this appendix you will find a list of IBM DOS/VS-specific features, what they do, and whether they are supported by ACUCOBOL-GT through the command line option, "-Cv."
IBM DOS/VS COBOL compatibility is available only with Version 5.0 (or later). Therefore, the compiler aborts with its "usage" message if both "-Cv" and a backward object compatibility option, "-Z32" for example, are specified.
