Alternative Modest PARM Proposal:
As the problem is (old?) programs that cannot cope with
longer parms than 100 bytes, among them IBM module apparently,
that's the problem that needs to be solved.
Not exactly on the IBM programs. There was a suggestion to allow a
longer than 100 byte passed parm by changing the passed parm list
from one entry (pointing at the current 100 byte-max JCL PARM) to a 2
entry parm list (with parm 1 staying the same and the added parm 2
pointing at the extended JCL PARMX [or whatever IBM wants to call it]
contents).
The IBM Program module issue is that many of the IBM Utilities can be
called (as opposed to JCL EXEC PGM= Launched) with a multi-entry
Parmlist (with parms 2 and on pointing at DD Name overrides). This
would conflict with using Parm 2 to point at a PARMX entry. The
SIMPLE solution is to have the INIT and JCL Parsing code suppress the
passing of a PARMX to these Utilities (IBM knows who has this
optional parm list support and can thus build the needed suppression
list by populating it from a PARMLIB member).
