A code resource is almost identical to a "real" application, the only
significant
differences are that it does not have the usual startup code that tells the OS
to
"jump to main" or PilotMain in this case. This means that if you are using
CodeWarrior
do not try to link in StartUpCode.lib
You can write the code in whatever editor you like, but you still need a
compiler.
CodeWarrior lite may have all the options necessary, I have never tried it,
I am reasonable sure that GNU's PRC-Tools have the functionality required.
Important points to remember:
The program type must be 'sdrv' not 'appl'
The resource ID must be 0
There is no "PilotMain" function, it is replaced by DrvEntryPoint. For
CodeWarrior see
Project settings, Target, 68ktarget, PalmOs Code Resource, Entry Point
Hope this is helpful,
Good Luck,
