For Internal Xerox Use Only
1. Interactive usage
Release a mouse button on top of an entry in the menu means selection of this entry.
2. Client usage
The module exports one single procedure. Calling it makes a pop up menu appear. The machine is monopolized while the pop up menu is visible. The user can only select an item in the menu, or discard the menu. Use the menu package such, that discarding the menu does not cause any action to happen.
The default parameter causes a cursor displacement such that this entry is selected at call time.
A NIL label will use a pop up menu without label.
