I like John's idea. I think that this idea was discussed before with the suggestion that JCL PROC/SET variables be stored in a special ASASYMBM table.
Re: "Use of symbols in the operand of SET is not supported." - really? This works fine: // SET PRFX=SYS1 // SET MACLIB=&PRFX..MACLIB // SET AMACLIB=&PRFX..AMACLIB // SET LINKLIB=&PRFX..LINKLIB Kirk Wolf Dovetailed Technologies http://dovetail.com On Tue, Nov 3, 2009 at 10:04 AM, Paul Gilmartin <paulgboul...@aim.com> wrote: > On Tue, 3 Nov 2009 09:33:01 -0600, McKown, John wrote: > >>I still say dump the request for a change to PARM length max for JCL and/or >>the PARMX=.
