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]
