hi Fabio,

Well I guess it will be a lot faster than writing your own preprocessor which would be a RegEx search with a huge pattern consisting of all the defines, skipping the defines that are in a string, except the [] string of course. (leaving aside the defines based on other defines)

Oh, btw, I'm writing a RegEx class in vfp for fun in my spare time ;-)
