Actually yes and no - they use AMX which is multitasking, but no, you
can't use them yourself apparently due to a licensing thing where they
can't let you talk to AMX directly, and/or just certain features - the
kernel was built with N threads/tasks and Palm uses every one in the
OS. If you licensed PalmOS itself, AND AMX (www.kadak.com which I
think is a $5k license that includes source) you might be able to do
something.
That said, there is limited interrupt and multitasking available. The
Serial driver allows you into the interrupt level. If you do the
event loop, you can build a task manager around it (actually it is
supposed to be event driven, so is a different paradigm, but most
"multitasking" can be mapped into event handling - I have a MIDI
sequencer which has to work like this).
