The uses for OPSYN are pretty hard to come by.  It could be used to convert
every BAL(R) to BAS(R) if you needed to clean up 24-bit linkage addresses in an
XA situation.  Just the other day I used it (for the first time ever) to
supress recognition of BAS and BASSM in an SP1 environment.  The assembler
instead calls BAS and BASSM macros I wrote which generate the appropriate
non-XA instruction.
