The PtrUpdate function creates the pointers which establish logical relationships. Logical pointers are created between a logical child and its logical parent and between paired logical children.

The two adjustments which may be performed are:
The number of segments deleted and created because of these adjustments is included in the detail report listing. The number of logical child segments updated with a valid logical parent pointer is also included in this report. These counts are listed by segment name.
