Actually $ (which I always call "dollar") is in the language because
some early implementations of Fortran allowed it in identifiers. It
has never had any standard meaning in the language. In other national
variants of some of the character sets Fortran has been implented
with it would have displayed diffferently than $ anyway. For the most
part it would be OK to remove it from the language standard since
it would still be usable under the provision:
Additional characters may be representable in the processor, but may
appear only in comments (3.3.1.1, 3.3.2.1), character constants (4.4.4),
input/output records (9.1.1), and character string edit descriptors
(10.2.1).
I would object to that. Back in the Fortran77 days, I ALWAYS used "$"
as the continuation mark. Why? Because a) it was guaranteed to be
there by the standard and b) (with the exceptions you mention) it
couldn't be used for anything else.
