There is a "Quick Reference Card" that can be downloaded from: http://www.microchip.com/10/Tools/picmicro/code/mpasm/index.htm which contain a listing (and brief explanation) of the assembly mnemonics, among other things. If you want a complete description though, you really should just grab the full microchip data on the chip you are using, as other have suggested. Corey Drechsler
