F90/95 supports lower case, but (except when string data) not as
separate characters. That's pretty much the way most F77 compilers
worked - if the system supported lower case characters, they could be
used as aliases for upper case. I used a FORTAN IV compiler that
worked the same way.

Which compiler did you use that enforced upper case?
