I have a program written in assembler and it does not contain any CICS command level calls. I assembled this program once only, then I linked it as two versions, one to run in batch mode and one to run under CICS.
How can this program determine whether it is running under CICS or batch? Can you suggest, in general terms, how I would approach the coding of this test? I want a single piece of program code which works correctly under both batch and CICS.
If you must have a chunk of assembler code that can be used in two places, structure it as a copybook and thense include it in two other programs -- one that can be compiled for CICS and the other for batch.
If you really want some control as to which code paths are used, code the source up as an assembler macro which can take a parm of BATCH=Y or N and so, emit the different code that way.
