The 16F84.INC file (or whatever you're using) is where W and F are defined as 0 and 1. As long as you have included this file at the top of your program, it's automatically defined and will work (should work) with MacPIC or whatever assembler you choose. --Andrew _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- http://www.piclist.com#nomail Going offline?
