RW 6.12.00
I was adding some extra text to my routines and added the TPErase instruction in my UNDO handlers so I would always have a blank screen in case I aborted. Whenever this instruction is used in an UNDO handler though, it generates a run-time error and says that the instruction is not allowed. The section of the Rapid overview manual on UNDO handlers specifies that the program pointer can not stop, so I understand why some instructions like WaitUntil can't be used, but I'm curious as to why I can't use TPErase.
