This is hardly such a novelty: for a half-century the Assembler
could invoke the compiler with up to 32Ki-1 bytes in PARM.

I'm sticking with the consensus of 100 bytes. But do you mean that CALL,
etc. can invoke COBOL with the much longer PARM? That this has been
true for many releases?

In your first ply you said that the motivation was that the requestor
was too close to the (255?) 100-character limit to accommodate one
more option, so a different option provides no relief. (Well, minimal,
insofar as it's shorter than the 7 characters in "OPTFILE".)
Has PARMDD been suggested to the requestor? AFAICT, the only
distinction between EXEC PARM= and PARMDD is that the latter
can not end with a blank.
PARMDD should provide the solution; the RFE should be rejected.

Tom has said COBOL has no such limit, so no problem. The JCL limit
is unlikely to change (although that should have been done long ago.)
