A83: Re: Re: op commands
Well...Thank you for helping me out. I was serious about your ASM guru
though. I have been trying to learn ASM with no luck for seriosuly 2 years.
I havent been trying to hard, but then again, I probably would have figured
it out sooner if I had. ;-) All I needed to do was take a course on C and
immediatly following that I knew everything you were talking about.
Thanks again!
Jake
