Runtime Considerations › Map Inquiry and Modification › Temporary VS Permanent Modifications

Temporary VS Permanent Modifications

The difference between temporary and permanent map modifications is:

• Temporary modifications apply to the next mapout operation only.
• Permanent modifications remain in effect for all mapout operations for the map until explicitly revoked by one of the following actions:
  • A subsequent, overriding map modification statement is issued for the map at runtime
  • The map control block is reinitialized (as when the map is used by CA ADS dialog or CA IDMS application program)
  • The application program (task) that uses the map terminates
  • The dialog that uses the map either terminates or becomes inactive in the current application thread

Note: If both temporary and permanent modifications are specified, the temporary changes override the permanent changes for the first mapout operation only.
