doEvents

I do not believe in prescience, but Hayden McKay comes close to shaking 
my "non-faith". In response to my earlier request for help, he recently 
replied:

<snip>
Place this at the top of all 'while & for' loops
(after any delcared values)

doEvents(0)

This will keep everything active while loops are running.
This also prevents the app to "not responding" incase of a very long 
loop.

I did not use this info because "guru" and "help" did not turn up any 
references to it. Then, my system got hung in a problem which I have yet 
to decipher, and I had to literally "pull the plug" to stop it.

I still don't know anything about "doEvents", but I am convinced that I 
need to learn. Is it an undocumented feature?
