Hello,
there are different approaches possible, that are quite common among the
Palm developers and that can to certain extent replace missing OS support.
You can start a long computation (what you call 'background process') and
periodically run the event loop. E.g. you can supply some callback to the
process. The process must call it frequently. Further you need some
interaction (protocol) - it should include the progress information and a
possibility to abort.
Alternatively you can start from another end: Run the event loop and
periodically pass the control to the process. A suitable moment to do it is
the reaction to the nilEvent as this represents idle state. The condition
for this method is that you can carry out the process in small discrete
steps.

Hi pedro,
Thanks for you reply!
Actually, I want to keep running some process in the back goround and allow
user to interact with Forms (User Interface) at the same time.
I wonder if any of the solutions that you have suggested is suitable for
this approach!
Thanks,
Keyur
