-> I suggest you look at using OS/2's REXX, it is ideal for doing this
-> type of work. I use it to serialize events that MUST happen in a
-> particular sequence, or when 2 different events CANNOT happen
-> together. When using the REXX SysSleep() call to wait for a flag,
-> exactly 0 CPU cycles are consumed.

Could you please send me an example of this? I have no idea how to use
REXX. Do you compile it? I'm duhhhh. :)

-> Then look into using SEMAPHORES or PIPES for triggering the events
-> rather than flag files. This means SysSleep() becomes redundant and
-> your system becomes a true event triggered environment.

The only thing I can do is a flag file... because half of the triggers
to this window will be coming from machines other than OS/2 computers...
so named pipes won't work. :( WEll, between HWAIT and Rexx, I'll come up
with something. :-)
