Specifies the frequency of the automatic save function during Change All and Repeat All operations; that is, the Change All/Repeat All checkpoint frequency.
When AUTOSAVE is set on, ZDT/IMS:
  • Increments a count by 1 each time a segment is updated during a Change All operation or inserted during a Repeat All operation.
  • Issues a checkpoint when the count is equal to the Change All/Repeat All checkpoint frequency.

When you specify two values in parentheses, separated by a comma, the first value is used for BMP mode and the second value is used for DLI mode. When you specify a single value, this is used for both BMP and DLI modes.

This parameter is optional. If it is not specified on the HFM1POPI macro statement, ZDT/IMS uses either the value specified on the HFM1POPD macro statement (if specified on that statement), or "(100,100)" (otherwise).

If you do not want the user to override the value you specify for this parameter, set UAUTOSAV=N.
