Online Mapping Facility

The online mapping facility (MAPB) enables you to compile maps in online mode. You use the following screens to define a map:

1. Main Definition screen──Used to specify basic information about the map, including the map name and the dictionary in which it resides.

   Note: The Main Definition screen records are called internal records and refer to records in variable storage. A map's external record is the record that describes a layout of data in the input or output file. Record elements in an external record map to data fields in internal records. If an external record element maps to itself, you do not specify the external record on the Map Definition screen.

2. Field Definition screen──Used to specify the external record. If the external record participates in several files, you also specify the applicable file.

   Note: Once an external record has been associated with the map, you must explicitly select it to display it.

3. File Field Selection screen──Used to select record elements in the external record for participation in the map and for editing.
4. File Field Edit screen──Used to associate an external record field with an internal record field and to specify special editing and error handling characteristics.
5. Map Definition screen──Used to compile the file map load module.

The MAPB screens are shown below, accompanied by notes on new and changed fields and functionality.
