Looks like the kind of job for perl or python... not fox.

I've come to love python for this kind of jobs. It's an easy language with powerful string and regex manipulation. Buy a short book on python, read the file manipulation and regex chapter. It's easy to learn and will not duplicate on your vfp skills.

Those languages (python and perl) are string processing champs, indeed.
