Map Library Structure

The Map Library is a keyed file that contains:

For each map defined to the system there is one map registration record. This registration record contains global information that registers the unique map name, and other identification data. It also contains information about the system data set where the source statement file can be located.

One or more load module records exist for each map. These records are compiled from the map source statements, and represent the amalgamation of the logical and physical data structure information into a form understandable by the Map loader.

The source records contain the ASN.1 source code from the last successful compile of the map.
