The "midrange reference manual" has a section devoted to it, and data sheets to individual chips also have such a page, and several pages following are devoted to describing each instruction in detail and providing examples. There was also a handy folding card included with the PICStart Plus programmer that works well as a handy quick reference. Just to pull out an example, for the PIC16F84, data sheet "DS30430C", section 9, page 56 has such a table describing every instruction, the mnemonics, the opcode in binary, and what status flags are affected. The page before and pages after are also useful as well. Jeff -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
