I am completely new to REXX and am trying to read up about it. I am trying to write a REXX to generate a JCL as a member of a PDS. I would also like to parse some parameters from the JCL that would run the REXX. Could someone please provide a sample REXX program that might do something similar to this?

Spoorni,
for starters, in which environment do you expect that REXX to run? TSO batch or ISPF?

This is one way of building a pds member:

address TSO
"delstack"
cc=BpxWdyn('alloc da(dataset(member)) shr rtddn(xdd)')
queue "data-record-1"
queue "data-record-2"
address tso "execio" queued() "diskw" xdd "(finis)"
cc=BpxWdyn('free dd('xdd')')
"delstack"

Of course you should test the success of the various commands.

and one way of parsing parameters:

parse value ' 'translate(arg(1)) with p1 ' PARM1('parm1')' p2
parse value p1 p2 with p1 ' PARM2('parm2')' p2
if p1 p2<>'' than say 'Invalid parm:' space(p1 p2)
