ABSTRACT:
A system and method for determining whether or not a non-system pointer is equivalent to a system pointer. The system and the non-system pointer each have pointer IDs. The system first determines whether the pointer ID of the non-system pointer is in a table of pointer IDs and flagged in the table as being equivalent to the system pointer. Whenever the pointer ID of the non-system pointer is not in the table of pointer IDs, the system determines, based on the shape of the non-system pointer, whether the non-system pointer is equivalent to the system pointer.
