Loading a Map

During the load phase the contents of the load module records are reduced to an internal format that can be used by Mapping Services. Since references to imported definitions are resolved on load, the load module containing the imported definitions must be previously compiled.

Any inconsistencies in either the ASN.1 logical structuring, or the Mapping Services local form definitions, causes the map load to fail.

Once compiled, maps can be loaded from the Map Library to validate that they load without problems. Maps are normally loaded automatically when they are first referenced, requiring no action on your part. You might, however, want to load a map, using the LOAD MAP command, to determine if it can be loaded successfully.

The UNLOAD MAP command may be used to remove an old copy of a map from storage. The SHOW MAPS command displays a list of maps that are currently loaded.
