Automatic reset?

Can someone please solve this mystery?

The mystery is how a few of the Basic Stamps appear to have been
modified so that they cannot run their programs properly. It
functions normally except that it automatically resets in one of the
programs. This happened at the same point every time. I then reloaded
the programs, but without any change. Thinking it could be a
disturbance from somewhere in the circuit, I swapped microprocessors,
but the Basic Stamp retained the problem even in the €··'³new€··
circuit
board, while the "old" circuit board, now with the other Basic Stamp,
functioned faultlessly. The problem therefore is in the Basic Stamp
and the mystery is that when, at a certain point in the program
sequence, the program tells it to run another program, it goes to
program no. 0, i.e. resets. I cannot see any reason in the program
for this.

I am running a Basic Stamp BS2Sx in an amperometrc analytical
instrument with a micro-pump and micro-valve connected to the circuit
board, if this can be a clue.

Thanx,
Hans

    We saw something similar and putting 'END' statements at the end of each
    program page solved the problem. Hope this helps.
