I just checked in the include file for the 16F883 I have for an early=20 version of PICC I have on here (9.70) and for the internal oscillator=20 (no clock out) you put INTCLK. In case you don't know, all the bits are defined in install=20 directory->include->pic16f887.h (right at the bottom) --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
