I am not sure of being in a position to commit to doing this. For me, doing
so would make it a matter of honor to work on it regardless. A weird
aspect of my personality, I guess.
In any case, I don't know of any way to actually integrate PCRE into REXX.
It would be neat to be able to do
CALL *(REXXPCRE) 'PCRE VARTOPARSE MATCH.'
I would go with that one any time, but you will need a persistent LE
environment (i.e. use PIPI) if you do not want to compile the PCRE expression
every time you call it, etc. etc. I researched the thing for a while before I
