Description
The current number of pages in the Table B reuse queue (unordered files)
When record deletions occur in unordered files, a page is added to the reuse queue if the following conditions are true:
- Enough extra bytes of free space are available beyond BRESERVE to satisfy the free space required for the BREUSE parameter.
- At least one record number is available.
For more information about the reuse queue, see File design.
