Have you looked at the "Palm OS R Programmer's API Reference"? (See the
"Compatibility Guide".) It clearly describes when (under which OS version)
each function was introduced. At runtime, you can check the ROM version,
and you can also test for feature sets. Then, don't call any function that
isn't supported.
