I found a little problem with using "Set Procedure To". You can set procedure to any text file. Hmmm, I'd like to try and make this "idiot proof" but, as they say ... "make it idiot proof and they'll build a better idiot".


>WOW! Thanks for such a simple solution. I was using fread to look for a signature in the exe's per David and Georges suggestions. I also started to look for a signature in an "APP" but have yet to find something. In any event, your suggestion is great too. Thanks again.
