I fixed the problem. As it turned out there was no problem with my origonal code. The problem lay in the configuration of pin B0. I traced the bad signals I was getting back to that point with my oscilloscope and when I switched the functions of B0 over to C7 it worked as expected. Also, there is absolutly nothing wrong with using the SYMBOL command the way I used it in my origonal code. It simply throws in an alias name for a pin, constant or whatever and makes the program easier to work with. I also prefer to include the LET command as it gives the code a more finished look and in my opinion makes it easier to read.
