Robin,
The discussion (which I started) is about using a macro to reverse data
in the assembly so that it can later be used by a MVCIN to set an
eyecatcher.
You have apparently not read all the posts.

MVCIN is not a BIF in HLASM.
MVCIN is an instruction.
Don't confuse what is available at run
time with what is available at assembly time.
Is there an RFE for a REVERSE BIF in HLASM? Is there a PL/I compile
time REVERSE function?
