viewIdleScript in Palm OS?

[Palm Programming]

i'm writing a game and need to have a routine periodically called at a
regular interval. On the newton OS, I used to accomplish this by using a
viewIdleScript, which I could tell the newton to call every so many ticks
of the clock. How can one accomplish this type of periodic call on the
Palm OS? Thanks.
