Hi Kurt - "Watchdog" is a Tracy Allen pgm that's documented here -
Scroll down a bit... http://ftp.whtech.com/club100/ref/ My stuff is in storage right now, but what I did is use the background task interrupt to increment a secs/mins/hours counter, & display the result where the M$ blurb is located on top - Pretty easy...
