I think that the case munging of some things was due to the 3277. I vaguely remember that it would, originally?, only display upper case, but that the keyboard would enter things in lower case. And the caps lock sucked in that it wasn't a caps lock, but a shift lock which affected the numbers vs. special characters on the top row. So, TSO just decided to upper case most everything to help out.
I remember in the past when the 3270 (3278?) had the ability to display lower case, but had a switch to automunge lower case to upper. One person in particular would switch this on. Then enter a ticket about a JCL error due to an MVS problem. I flip the switch and show him that the JCL was in lower case. He then would curse at the system. Fix the error. Flip the switch back to "upper convert". Then repeat the same problem again (and again and ...) and enter another MVS failure ticket. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
