Librarian Exit Table

Librarian does support user exits under its Batch Update facility. The user exit may be common, or may be assigned to a specific master file. In order to configure this option, MFA references a reserved DD named LIBXIT$. If specified in the JCL, MFA builds a memory table to specify the Output Exit to be used for the given master file.
