This error is normally due to a jump instruction to an address of a function that lies
beyond the normal address range, which is 32KB from the current location. You can
avoid the error by adjusting the type of memory model that you are using within the
project. There are three memory models that are supported by CodeWarrior for Palm
version 8: small,large, and smart.
The large memory model actually generates a series of instructions that allows you to
make function calls beyond the 32KB range as opposed to the single jump instruction
that is used in the small model. The smart model is a combination of the small and the
large model in which the compiler will try to use the small model wherever it can in
order to avoid the code bloat caused by the large model. The code model can be changed
in the 68K Processor panel in the target settings for the project.
However, you should try to avoid using the smart or large memory models if possible
for performance reasons and to avoid unnecessary code bloat. One way to do this would
be to try rearranging your code in the Link Order tab of the IDE project window in
order to reduce some of the distance between certain function calls.
