LCHILD statement overview

The LCHILD statement defines a secondary index or logical relationship between two segment types, or the relationship between a HIDAM (or PHIDAM) index database and the root segment type in the HIDAM (or PHIDAM) database.

LCHILD statements immediately follow the SEGM, FIELD, or XDFLD statement of the segment involved in the relationship. Up to 255 LCHILD statements can be defined for each database.

Restriction: The LCHILD statement cannot be specified for the primary index of a PHIDAM database because the primary index is automatically generated.
