I'll just put a plug in here for my "porting 16F84 to 12C509" page. It mentions this curiousity of GOTO and CALL along with numerous other oddities. If you've trained up on the 16F84 chip and find yourself using the 12C series, this page is for you. Corrections welcome. -- James Cameron mailto:quozl@us.netrek.org http://quozl.netrek.org/ -- http://www.piclist.com hint: The PICList is archived three different ways.
