Some operating systems use '$' in identifiers.=C2=A0 Compile= rs sometimes have
an option to allow '$' in identifiers.

The '@' and '`'=C2=A0 characters are used for extension lan= guages.

I don't follow this. To which e= xtension languages are you referring?

=C2=A0 That is
you have a language that uses them much like the preprocessor uses '#&#= 39;
to find out where in the program text it should pay attention to them.

The use of these characters in C++ would have negative consequences.
