Chris,

If you are referring to the GOTO in the following snippet, yes.

' minutes roll over to main program
   OPTION=$C8
   p=1
   goto Start

The program appears to successfully jump to "Start" (so I assume that the OPTION=$C8 is 
executing properly and disables the RTCC timer).  From the LED trace it also appears the the
"Start" sequence executes properly UP TO the OPTION=$88 (RTCC enable) where the program
stops.  If I hit reset on the dev. board the program commences at start and the the OPTION=$88
does execute causing the program to jump to org 0 initiating the interrupt timer routine.

So, at the end of 1 or 10 minutes, depending on how I set the value in the loop, the sequence falls 
through the loop executing the OPTION=$C8 and the jump to "Start".  Consequently, it appears that 
either the OPTION=$C8 or OPTION=$88 or both do not execute and that the only way to force the a 
second or n number of enablings of the timer is to hit reset.

I hope this clear.  As I said before, this coding sequence is not rocket science, so I am at a loss to
under stand why only a hard reset is the only way to relaunch the timer.

As always, I appreciate your continuing help.
