Hi John,

Not sure why you want to do this, but what about just:

For i = 1 to 10
 i = i - 1
Next

Is there a way to determine when the script engine has timed out with the script above?

By default there is no timeout value, so it won't actually time out using just the code above.  You can set the number of seconds before timeout using     wscript.timeout=numberofseconds    but there is nothing notifying you when that is reached.

You can see what I mean by opening your task manager and sorting the processes in reverse alphabetical order. when this starts running you'll see wscript.exe in the list, and after it reaches the timeout value (10 seconds) it will quit. I'm echoing the timeout value so you can see it has the default value of 0 (no timeout) then you can see the change implemented:

wscript.echo wscript.timeout
wscript.timeout = 10
wscript.echo wscript.timeout
For i = 1 to 10
 i = i - 1
Next
