Determining Available User Table Data Space
To determine available user table data space, you must take several nonuser table data space allotments into account.
First you must determine how much space these allotments account for and then you must subtract them from the total available table space.
The nonuser table space allotments that must be accounted for are those in the following list.
Note: Data blocks that are not modified in place are not written to the depot area.
The following topics describe specific space requirements and provide equations with which to determine variable space requirements.
