If you use MPLAB or the HiTech IDE you choose the chip and the number gets passed to the compiler. If, like me, you use a makefile or compile from the command line, you pass the part number implicitly, as in "picc -16F690 filename" Cheers, Bob -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
