Keep in mind, that on Palm OS, programs are not loaded and unloaded (except for those on external cards). And they receive notifications and get events on a regular basis. But only the 'foreground' program has access to globals (although there are tricks around this restriction). You have to ensure the 'background' application(s) don't impact the the current 'foreground' application. One good time to run your task is after you get the "going to sleep" notification and then use alarms to run periodically while the unit is asleep. Watch out for battery usage though!
