This is largely true, but there were f77 compilers that, by default,
would take lower case characters and treat them as distinct from
upper case (i.e. following the C language conventions).
Although there have been numerous discussions about this here in
c.l.f over the past 20 years, the above is generally regarded as an
extension of the f77 language. On the other hand, treating lower
and upper case as indistinguishable was *not* an extension to the
language, but rather falls into the category of source code
transcription, which is explicitly mentioned as something that is
not covered by the standard. F90 and later specified that lower and
upper case characters should be indistinguishable (except for
character strings, of course); this is compatible with the f77
standard, but obviously not with those with the extension that
treated lower and upper case as distinct.
