Just seems like a lot of discussion trying to pass 22 arguments, when the limit
is 20.
And 20 arguments is still wildly excessive. It's long been accepted that
any more than 7 arguments are difficult to comprehend and an alternative
design should be implemented.
Even 7 is excessive, I don't like to go beyond three arguments before I
redesign to use a context. This has been solved in other languages by
using design patterns like builders but the problem
with REXX is that it doesn't support object types so you can't pass
contexts around. Stem variables don't cut it because you can't pass them
to external functions.
After that it's merely a question of how you can convey the information using
whatever means you have available.

If you need to include all 22 arguments, just make the last one bigger and
parse it a second time to get the results.
For example:
000001 /* REXX */
000002 rs = ALERTSN(SEV,TYPENAME,ELEMENT,DESC,STATUS,STSDESC, ,
000003 SUBSRC,SOURCE,LOCATION,SYSTYPE,PLTFTYPE,IMPACT,HOST, ,
000004 MONENV,RESOURCE,EXTRINFO,ACTIVE,CLOSING,FTPERR, ,
000005 APPLTYPE APPLNAME UNIQUE)
000006 EXIT 0
...
Notice that the last argument is separated by spaces to combine them all as a
single argument.
This depends on a couple things:
o That ALERTSN is written in Rexx, or at least that the OP has the source so he
can modify it.
o That the "combined" arguments contain no internal blanks, which makes parsing
more complicated.
