Re: Fortran 77 alphabet character $

If I remember correctly, some compilers allowed the use
of a $ sign as an extension. It was allowed only as the
first character. I do not know what the default type
would have been.

Other compilers I have seen used it in formats: we now
use ADVANCE='NO' for the same functionality.

It seems to me your professor has a problem here. My
suggestion would be to:
- Find a letter in the alphabet that is not used that
often as the first character (a Z perhaps?)
- Use that to replace the $ sign
- Make sure that there is no overlap with existing
variable names. You could use a tool to create a list
of variables then.
