I was trying to write some code for freefem and immediately ran into a problem that "_" does not seem to be allowed in identifiers.
I went looking through the documentation and could not find a definition for valid identifiers.
It is probably safe to say that it is something like
[a-Z][a-Z0-9]*
i.e. only letters and digits.
