Public Jump Table

A list of branching instructions for the microprocessor, indirectly pointing to native functions. For each version of the ROM in Newton OS 2.0 and later, the functions always reside at the same offset in the jump table. Native programs can call these functions via the public jump table and they will work on every Newton OS device. The public jump table also contains a series of branches pointing to the patchable jump table.
