I just checked out the web site. What is it with Parallax and there
rewriting of the PIC opcodes? It looks like their development system only
supports there re-writing of the assembler to the "Intuitive Intel like
instructions". For one I've never found the Intel instructions to be
anymore intuitive than anyone else's, and for two, the last time I looked at
the Parallax instruction set I thought I read that there was not always a 1
to 1 correspondence of mnemonic to opcode, some mnemonics generating more
that one opcode. If find that especially irritating...

Sorry, I just had to bitch.
