Unless it was changed by Apple, the BASIC.SYSTEM interpreter has it's own
version of FRE that is extremely fast.  To call it, instead of FRE(0) issue
the following ProDOS call:

xx PRINT D$;"FRE" : REM Where xx is the line # and D$ is a CONTROL-D

This can be called as often as desired but should be often enough that the 
Applesoft FRE(0) routine be avoided.
