I am quit sure, but I am really curious that if Palm OS is not a multitasking OS,
how the Chinese system of CJK system to work under Palm OS?
Even the hand-writing organizer, it will detect the user pen down event on the silk
screen.
That really interesting, right?

No, the PalmOS is not multitasking for user applications. The core OS
kernel on which it runs supports a fixed number of tasks, but only one is
reserved for the user interface layer in which apps run.

Accidental overwriting of database memory used by other applications is
prevented through a memory manager which write-protects all of memory other
than the application heap and stack, allowing writes only through checked OS
calls.
