I have read the thread as of 3 PM Atlantic (not Eastern Standard) Time on Feb. 24, 2015 and would recommend as a first step to check your compile options for the MVS and VM compiler to see which ones differ. This may be difficult in some cases because the option may be specified differently. I also would be surprised that NORENT is a good idea in CICS. I know that one of the main advantages of the changes in COBOL starting with VS COBOL V1.4 was the ability to have REENTRANT modules in CICS. Check your CICS compile proc against any that are recommended by IBM. Definitely have someone who understands the options used for both compilers review for differences. I suspect that the ARCH level is not the problem because the MVS and VM compiler probably generates code that is pre ARCH(6). Using a higher ARCH level if feasible in the destination environment is good but not relevant to the problem here. Also check any of the CICS precompile and execution time options for differences.
