DFSMAP statement overview

The DFSMAP statement defines a map that references a control field for a set of map cases.

Each map case in a set references the map by the name defined on the NAME parameter in the DFSMAP statement.

The map references the control field by the external name of the field on the DEPENDINGON parameter of the DFSMAP statement.

Optionally, the name of the field specified on the DEPENDINGON parameter can be a field defined in the segment specified in the CTLSEGNM parameter.
