I discovered something interesting about the Prime today

[Michael de Estrada]

I don't know if the Prime always worked this way or if it is something that was implemented in the firmware update, but the Prime will rename all EXPORTed routines in a program if it is duplicated by saving it under a different name, provided the routine names are all extensions of the program group name.

Specifically, I had a program named Beam that contained EXPORTed routines named Beam_Solve and Beam_Main. When I saved a copy under the new name Beam2, then the routines were automatically renamed Beam2_Solve and Beam2_Main. Also the call to Beam_Solve from Beam_Main was revised. This avoids any conflicts that would occur if they had retained their original names.
