Hello, all,

I seem to recall that it was documented and supported to port CICS/VS 
applications source code (written in BAL or COBOL or PL/I) from CICS/OS/VS to 
CICS/DOS/VS or vice versa, and then recompile the programs on the new target 
platform.  I think this was true for both MACRO Level CICS as well as Command 
Level CICS applications.

What I want to know is whether the executable code statements generated by the 
MACRO level macros, or the source code generated by the Command Level 
Translator, was ever compatible between OS/VS and DOS/VS, or if there were 
differences between CICS/OS/VS and CICS/DOS/VS in this area.

IIRC, the code generated by the OS/VS COBOL compiler was not identical to or 
compatible with that generated by DOS/VS COBOL.  Same for PL/I.   At the very 
least, they had vastly different runtime libraries.

Can anyone clarify these issues or point to any relevant documentation or IBM 
manuals?

Thanks in advance,

Mark S. Waterbury
