Hi Aaron,
I believe the owner ID is used by PalmOS to identify who has allocated
any given memory block. This is used to cleanup upon application exit,
avoiding memory leakage.
I don't have the docs here right now - I'm on vacation :-) -, but if I
remember right, passing a launch code of 0 is like using the application
as a subroutine. You don't have global space allocated for you, nor
stack space by the way.
In your situation, I'd probably use the normal launch code. I don't know
if you can use SysUIAppSwitch, but that would be the safest way.
SysUIAppSwitch will post an appStopEvent, though, causing the calling
app to close (if it doesn't it will never launch the other app).
