Gene: And, for the record :-) the PPC ROM routine does not have the RTN END combination here.

To my knowledge (?) there is only one "bug" in the PPC ROM code. The LBL BE routine has a GTO BE instruction at the end of its loop instead of a GTO local label.

Rather unfortunate, since it must travel the global alpha label chain each time...and a number of routines use the BE routine.

But I am not aware of any other bug ?
