One sidenote. IIRC you cannot access the stack on the pic16f devices. This is only possible on pic18f devices. There is a wonderfull appnote about that on microhcip website. I managed to have a small scheduler which saves the context (stack, sdcc-stack via FSR1,FSR2, and some regs) of up to 4 tasks running on a pic18f. If you like i can send you the code.
