Getting the old QSAM assembler code to run in AMODE 31 is fairly trivial (probably -- I have not seen the code). Best case no code changes whatsoever are necessary.
It is RMODE ANY that takes some effort. So you should be able to make AMODE switching a non-event.

DATA(31) should allow most of the callers storage to reside above the line, and switch to below the line processing only when calling the assembler routine. Would excessive TCB switching result if the assembler program is invoked repeatedly for file i/o, or does that not come into play?
