The following program works correctly on ZX-24n, ZX-24ne, and ZX-1281e.

Sub Main&#40;&#41;
	Debug.Print "start"
	Call OpenWatchDog&#40;7&#41;
	Do
		Call WatchDog&#40;&#41;
		Call Sleep&#40;2.0&#41;
		Debug.Print "wakeup"
	Loop
End Sub

However if 8 or 9 is used as a parameter to OpenWatchdog then the processor continually resets itself.

Confirmed. In actuality, 8 and 9 have the same effect as 0 and 1 - too fast for the periodic watchdog resets thus yielding the continual reset behavior observed..

The workaround is to use &H20 and &H21 in place of 8 and 9, respectively.
