There is an illegal V
-memory pointer in WY5 or WY6. For example:
— WY5 = 1 and WY6 = 100 indicates
pointer
overlap.
— WY5 = 0 indicates pointer out of bounds (pointer < 1).
— WY6 = 39789 indicates pointer out of bounds (pointer
≥
32767).
•
There is a profile data error in clamp closing, injection, or pack and hold
