  I hope this isn't too far off topic.

I am wondering about the history of lower case letters
in programming languages, and especially about case
sensitive languages.

The first I know about is C. Ones I knew before then
didn't allow then at all, though it might be that some DEC
compilers would ignore case.
[This is an interesting question. The IBM 7030 Stretch had
an upper/lower case character set, although I don't know how
much software used it. Algol60 was specified in lower case
but most implementations were upper case only. I can't think
of a language before C that was actually implemented in lower
case but I wouldn't count on it being the first. -John]
