Spot compatibility issue before run-time

Link-edit message IEW2576I is issued by z/OS BINDER and program run-time failed with S0C1.

IEW2576I 5034 RESULTANT AMODE( 24 ) OF ENTRY POINT AND RMODE( ANY ) OF SEGMENT 2 MAY BE INCOMPATIBLE.

Since module should have RMODE(24) if it is called by program in AMODE(24), there must be compatibility issue as flagged by message IEW2576I for AMODE(24) entry point with RMODE(ANY) segment.

With default compiler option RMODE(AUTO) and RENT for COBOL 6.2, the executable is created with RMODE(ANY) by default.

When main program (e.g. Assembler program and COBOL 4.2 main program) in AMODE 24 calling COBOL 6.2 subprogram in RMODE ANY, the main program fails with S0C1 in run-time.

It is easy for user to ignore informational message with link-edit step ended with RC=0. It will be great if there are other choices to help user to spot compatibility issue and fix it before run-time, e.g. changing IEW2576I into IEW2576W with the associated RC update.

    It's critical importance for users to realize that the program object produced by binder having the IEW2576I situation, which will cause S0C4/S0C1 abend when executing. And this serious problem could be avoid at binding step if the binder could issue a warning message with non-zeros RC. Please enhance this function as soon as possible. Thanks!!
