Hi Brian, If you mean the book by Scott Edwards, yes, I have had a copy for many years. There's a chapter with program listings and explanations of all the commands that the Basic Stamp has, written in assembler. It's very useful for someone wanting to move from the Basic Stamp to writing PIC assembler, but with one serious caveat: Parallax mnemonics! Not Microchip! Some of the routines have a very strange (at least in my opinion) programming style. There are lots of useful routines there, though, and Scott is a good writer. I found the book useful when I was starting out with PICs, when there were very few books on PIC assembler. Now there are many good books to choose from, and Parallax mnemonics are not useful to many people(confusing even). -Bob At 07:42 PM 9/16/98 -0500, you wrote: >Does anyone have the pic source book?
