I thought the question was asked perfectly correctly and civily in
the original post. Don't see why Jason is getting the third degree

Jason, you need to be very aware of what the stack is holding. You
can View/Hardware Stack in MPLAB. I've done stack manipulation
very successfully with other micros but not had need to do it on the
18F yet

AN818 specifically says

"Having access to the stack allows access to the return addresses
of interrupts and functtion calls. Thus, the program direction can be
changed"

Didn't hurt did it ?
