I'm having trouble finding what's excluded from use. Is there no list of
forbidden characters? I wanted the macro names to correspond to that of the
charts. Example "1A) MS" ... without the quotes. When that was rejected, I
assumed the bracket was the issue and rewrote to this: "1A_MS". No luck
either. So I assumed numerics as first charter were forbidden and chose:
"Chart 1A_MS". Rejected!

Help please.
