Thanks for all your help. Regarding the code you posted. You'll have to fogive my ignorance. Could you break down your substitution line. I don't really understand what it's doing. I ran the code. Not sure how much faster it is 'cause I stopped it. My results were wrong. The substitution isn't quit right. I need to be able to look at every 2 bits and then determine if they are a 11 or a 00 then replace and move on to the next 2 bits.
