Map Occurrences

Map occurrences stored in the data dictionary associate record elements with panel field occurrences for existing panel occurrences.

Establishing Map Occurrences

Map occurrences can be established in the data dictionary in any of the following three ways:

• By using the CA IDMS online mapping compiler
• By using the ADD MAP or ADD MAP AUTOPANEL statements of the CA IDMS batch compiler
• By using the ADD MAP statement of the CA-IDD DDDL compiler (such maps are documentational only);

  Note: For more information, see the CA IDMS IDD DDDL Reference Guide.

Map occurrences are stored in the DDLDML area of the data dictionary.

The CA IDMS mapping facility online and batch compilers can modify or delete map occurrences from the data dictionary.

Considerations

The following considerations apply to the modification or deletion of map occurrences:

• Deleting a map occurrence that was generated by batch compiler statements for manual panel definition does not affect the associated panel occurrence.
• Deleting a map occurrence that was generated either by either the online or batch compiler statements for automatic panel definition affects the associated panel occurrence:
  • The associated panel occurrence is deleted unless the panel has been associated with additional map occurrences.
  • The associated panel occurrence is not affected if the panel has been associated with additional map occurrences.
• Map occurrences that are created by the online or batch compilers cannot be deleted by the DDDL compiler; the DDDL compiler can be used only to modify comments.
