     I already have OnboardC, which I'm running in the Palm Emulator 
(and might move
to an actual Palm at some point), which theoretically can do any of 
the built-in API
functions - IF I know what systrap number to call. It has a header 
file containing *some*
of the PalmOS API, but a *lot* of the functions are missing from it, 
including some that
I need (Serial I/O). You're supposed to put code in your own source 
that says something
like

ReturnValueType  FunctionName(RVT Param, RVT Param, ...) SYS_TRAP(number);

where you look up the number in Palm documentation that I also can't 
find. (They're not in
the API reference either.)

     If your documentation includes these numbers and includes the 
Serial Port functions,
emailing me that section should do the trick. Otherwise maybe I can 
do something with
the header files; zip up all files ending with .h and email that.

     I'm converting some of my Palm software from PocketC, which 
requires that "compiled"
programs be run from the PocketC application itself or a runtime 
module, to OnboardC,
which produces stand-alone executables with their own icons in the 
main menu. (It's the
OBD monitoring program I wrote a couple of years ago.) The systrap 
numbers are to give
me access to the Palm API functions corresponding to the ones built 
into PocketC that
I had been using. (I suspect the PocketC runtime portion just patches 
into these functions
itself.)
