Wait command

[dunbarx at aol.com]

There are very legitimate places for "wait", though more robust code can usually be written with "send (in time)". This has been going on for 27 years.


Wait is blocking. An idle handler will be locked out just like everything else.



But a line like "wait 0 with messages does not seem to me to do much. Maybe retard the flow of execution a few microseconds?

Only reason I can think to put a wait command in a running script is to give a 
change for an on idle handler to be triggered. If you DO have an idle handler 
running somewhere and IT has a problem that causes the engine to exit to top, 
that might be your bugaboo.
