Memory Issues

[Ronnen Belkind]

Can some one explain the memory constraints on the Palm to me?

Specifically I am running into the following problem:

When I declare a "unsigned char Array[2048]", my application compiles and runs
fine.
If I declare a "unsigned char Array[4096], the application compiles, but crashes
when it gets
to the declaration.

Changing the code model to large does not help.  My code doesn't come anywhere
near exceeding the 64k single segment limit.

Any Ideas would be greatly appreciate.

Thanks,
Ronnen
