Frank,
Unfortenately, there are too many situations that the parser can't control with a Macro substitution, personally I would not try to bother. For instance your code looked like a 100% winner for producing an error but it wasn't. But what if the parser insisted it was a 100% faillure, no thanks.Yes, I realize the challenge.
And I think that all the others are correct, only use Macro substitution only when needed. A lot of times, there are better alternatives.
I must say that I do not abuse macro substitution. David suggested evaluate(), which works great in most cases. But it doesn't work in all cases, consider the following:
c = "copy file a.txt to c:\a.txt"
&c
evaluate(c)
Thanks,
Dawa
