I'm not overly fond of this suggestion, but I make it in
case it's of use:
Have you considered a CLIST wrapper? The user invokes a
CLIST which parses out the operands, and that calls the
REXX program with operands that REXX can understand easily.
With sufficient ingenuity you might even make a general
preparser in CLIST; if you do, it would probably be
welcomed on the CBT tape.
