Messages
A program that contains an out-of-line PERFORM, and either an EXIT
PROGRAM or GOBACK statement, will receive the following messages when
compiled with the CMPR2, FLAGMIG, and NOOPTIMIZE compiler options:
- IGYPA3205-W
- **MIGR** "EXIT PROGRAM" or "GOBACK" statements assume that ends of "PERFORM" ranges were reached under the "NOCMPR2" compiler option. This program may have different execution results after migration if used as a subprogram.
- IGYPA3206-W
- **MIGR** For more information about ends of "PERFORM" ranges, recompile with the "OPTIMIZE" and "FLAGMIG" compiler options. If no messages about ends of "PERFORM" ranges are issued, then this program will not have a migration problem with ends of "PERFORM" ranges.
Upon re-compilation with the OPTIMIZE compiler option, the absence
of any such messages indicates that the program will not have any
problem with an EXIT PROGRAM or GOBACK statement being executed within
the range of an out-of-line PERFORM statement, while the presence
of the following messages indicates otherwise:
- IGYOP3205-W
- **MIGR** "EXIT PROGRAM" or "GOBACK" statements assume that ends of "PERFORM" ranges were reached under the "NOCMPR2" compiler option. This program may have different execution results after migration if used as a subprogram.
- IGYOP3092-W
- An "EXIT PROGRAM" or a "GOBACK" statement was encountered in the range of the "PERFORM" statement at "PERFORM (LINE xx.xx)". Re-entry of the program may cause unexpected control flow.
