I tried the above program but received an "Invalid conversion in printf:" error. I changed the printf to print and the program ran great. I'm now getting what I'd expect out of the program and it's extremely fast. Thanks for all you time and patience. What would you do if you had an occation where the data wasn't on cut (ie. the first pattern was offset by 10 bytes) and the user had no way of knowing?
