It will work only when what you describe is done at the 'highest level', meaning not in a subroutine that is itself called. Then return address just stays on the stack, but it is never used. The PIC return stack is a simple push-when-call (or interrupt), pop-when return. It is 8 levels deep, whatever was at level 8 is lost when you push a new level 1. Whatever is at level 8 stays there when you pop. push(a): s8 = s7 s7 = s6 ... s2 = s1 s1 = a pop(a): a = s1 s1 = s2 .. s6 = s7 s7 = s8 Wouter -- http://www.piclist.com#nomail Going offline?
