Hi Jinx, Thanks for your take on this as well -- I just saw Olin's response. I have never used that style, but I can see how if you are very careful it can work well. I personally make enough coding mistakes so I prefer to leave as much "thinking" to the assembler. We all have our methods of doing things. :) Take care, Ken Pergola -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
