The first software i was using was the parallax assembler and i lerned the parallax version. Now am am still using it and somtimes i have to check what the parallax assembler is generating and what the original Mchip instructions realy do. It was the first time i have seen a processor with two different assembler mnemonics. The parallax version makes it realy easy, if it was your first RISC type processor. St.
