"in the beginning" there was the 026 keypunches, and upper case jcl. Dis you
ever try to multi punch lower case chatacters? The 1404 only had upper case
until the ucs buffer was added to the 2821 contoller. The old habits are
hard to break and "there was no need for lower case" The old microfiche had
lower and embarissingly showed lower case (1 ibmer lost his job over what
was "hidden" in lower case. IBM had wisely include loer case in their
character set with no way to show it.

Ahhh, I remember the good old days.... No shift keys, no lower-case - it
was so simple...

There are some issues with lower case - data set names cannot contain lower
case characters; a parm that inserts data for a data set name will be
rejected with a JCL error.

 It's also not clear what the JCL processor should do with lower-case.  Do
the programs that get invoked expect lower-case?  How many programs (in the
world) would have to upper-case items to properly interpret them?
Parameters like AMP, STORCLAS, MGMTCLAS,  and others added over the years
would have to be  modified to support lower-case.  It's not just "allowing
them in JCL" - some of these parameters are passed to IBM components, and
to vendor products.  Can you imagine how much work it would take to support
lower-case?
