Specifies the frequency of the automatic save function when editing databases; that is, the Edit checkpoint frequency.
When AUTOSAVE is set on, ZDT/IMS:
  • Increments a count by 1 each time an action key is pressed and data changes have been requested.
  • Issues a checkpoint when the count is equal to the Edit checkpoint frequency.

The valid range is 1 to 99.

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 "(1,1)" (otherwise).

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