>Ian if you're on this list, may I use a piece of the VAT lookup part of >your SKI source code? May I also tweak it a bit for my own prog : ) let me just say that that was my first program, and some of the WORST coding i have ever done. but if you want to use a horrible method, go ahead. but i would recommend if you don't want to write for sos, just use the detect routine in zlib in your own code. it is very well written (joe...).
