Hint: RXSUBCOM Caveat: A version is available with DB2 or there is the version available from: Open Software Technologies product REXXTOOLS/MVS
"RXSUBCOM: a function for dynamically maintaining host command environments. As with RXFUNC, RXSUBCOM pre-loads the load module associated with a function to enhance performance." [this is from the REXXTOOLS/MVS Documentation, but I also believe it applies to the DB2 version] Now the BAD (or "My Bad!"): Sorry, but I do not how to get a copy of RXSUBCOM or source, to you and second, I do not know how to write a package for RXSUBCOM. Maybe I should have said "Tease" instead of "Hint" above. :-) Basically what I am trying to say is that, YES, what I think you want is available, but how to get there ????????????? I HAVE NO CLUE! Maybe you will have better luck to find something out there about RXSUBCOM and its ability to update the "host command table?"

Or at least to dynamically load a rexx function module at the start of an exec so that it would be referenced in storage rather than being loaded/deleted when used, and then to unload it when done. I may be off base but it seems like a nice thing to do to improve the performance when using modules for rexx functions and not having to create a function package. -------------------------------------------------------------------------- Lionel B.
