I have a program which needs to return to stack level 0 from different stack
levels normally 2 to 5. Is there any way of purging the stack or is it not
necessary ? When in simulation MPLAB gives stack overflow after a couple of
itterations.
The timer 0 and a counter is used to recover to the main program loop if
there has been no user input for 30 seconds. The object was to stop user
leaving the module in a state where other inputs are ignored while user sets
up opperational parameters. This however exits to 'MAIN' via a goto not a
through clearing the stack properly. An exit to 'DIRTY_EXIT' could be made
then goto 'MAIN' but how do I clear the stack from an unknown level (2-5) ?

Help please Steve.....
