How can we support PalmOS 3.5 and 3.1 at the same time if:
1. When you creating a new project in CodeWarrior you have to choose
between following
a. Palm OS 3.1(English) Stationary
b. Palm OS 3.5 Stationary
Hence CodeWarrior will generate machine code targeting
either 3.5 or 3.1 version, but not both!
2. Beside different compiler setting Palm OS 3.5 handling forms
differently. If you use standard
code to handle forms it will crash 3.5 debug rom. At the
same time if you target Palm OS 3.5 -
prior versions will not function properly.
3. Palm OS 3.5 handle writing on the screen different than 3.1. If you
use standard approach which works for versions
3.0-3.3 you will crash 3.5 debug ROM.
4. Palm OS 3.5 using improved functionality for Bitmaps. But these new
functions are not recognized
by versions 3.1-3.3, they simply crash. If you use old
approach to bitmaps it gives errors in Palm 3.5.
