AFAIK, WORKING-STORAGE still only gets created once per COBOL program, on first call of the COBOL program. I think that what you need to use is called LOCAL-STORAGE, which is re-allocated on every call. However, that is not your only problem. COBOL (even Enterprise-level) is still NOT guaranteed or warranted by IBM to work in a real multi-tasking environment. In particular, the output message file, normally SYSOUT, cannot be shared among subtasks and you still may need an assembler stub to keep each subtasks's messages displayable somewhere. > But I wonder how to migrate the ASM-Subs nearly painless....

You do not need GETMAIN/FREEMAIN subroutines any more (LE has them), and you may or may not need the STIMERM subroutine either, depending on what your application needs to do (LE has a DELAY function, but only for integer seconds). There are LE callable subroutines to do at least some of functions that we used to write our own ASM routines to do. Check out the LE Programmer's Reference manual for your level of z/OS, it has a lot of interesting information you can use. It may be possible you that don't need *any* of your in-house ASM routines any more, so you would not have to migrate them at all.
