One of the questions which immediately come up,
which data type is $foo (implicit typing)
One interpretation of implicit typing of Fortran is:
I-N are integers, everything else is real.
I think the issue had come up

Update regarding implicit rules:
FORTRAN 77 standard clearly says that:
A first letter of I, J, K, L, M, or N implies type integer and ANY OTHER
letter implies type real
FORTRAN 66 standard has similar statement.
This

I already know that the following compilers do support $ as the first symbol:
Intel Fortran 9.1
Open Watcom Fortran 1.8
MS Fortran for DOS 5.1

Note that the following code
program test
a$a = 12
$a = 12! error
$i = 11
$b = 0.5
print *, a$a, $a, $b, $i
end
when compiled with ifort:

Note also that in the ATT assembly style for i386/x86_64 (the default in gcc),
leading $ changes the instructions.
movl a_, %eax
means read the value from a_ variable into eax,
movl $a_, %eax
means set eax to the

Confirmed. Checked 4.3.4 and 4.5.0, both complain about '$a'.
Question is, if this is allowed at all. In comparison: digits are allowed in
function names, but not as the first character; 'FUNCTION f3()' is valid,

Many compilers support $ signs as extension (ISO standard Fortran does not).
However, only a few support a leading $ sign. One of the questions which
