I have been running the TX_HEX2 subroutine that is in the example programs and had it work successfully. Now all of a sudden it prints $E for the second digit regardless of what the input is.  Watching it in single step mode, what is happening, no matter what the character stored in the tmpB2 register the W register is getting loaded with $FE.  I put in a \ Mov W,#0 command prior to loading the tmpB2 but to no avail.  It loads $FE in the W regester.
I tried moving the Subroutine code to another page, again the same problem. 

Anyone have any ideas?
