Decades ago, when I was new to TSO (and Rexx wasn't available), I noted
empirically
that TSO was insensitive to case for commands entered at the READY prompt. I
tried using this concept writing a CLIST. Overgeneralized. I got:
IKJxxxxE UNKNOWN COMMAND 'DO'.
Well, I had typed "do". The TMP tried to parse it asis, failed, then
translated it
to majuscule to issue the message, thereby obfuscating the nature of the error.
Somewhat similarly, if I enter on most ISPF command lines:
TSO ALLOCATE PATH('/dev/null')
I get:
IKJ....I PATH ('/DEV/NULL') NOT IN CATALOG OR CATALOG CAN NOT BE ACCESSED.
Slightly different in that the harmful translation is performed *before*
attempting
to elaborate the command. ISPF should *never* convert the case of the TSO
command; just pass it to the TMP as typed.

ISPF is well aware of terminal code pages and filters nondisplable characters.
ISPF support was glad to fix by APAR an error I discovered in this processing.
Don't know about SDSF from the TSO READY prompt.

Ouch! You'll be in a thicket of code pages and CCSIDs. They *might* provide
CP037-based list of characters and hex code points. How useful would that
information be? I doubt they'll respect case in operator commands even where
it matters, such as UNIX mountpoints.
