MPE XL Native Language Programmer's Guide

Chapter 6  Implicit Language Choice in Subsystems 

Two NLS job control words (JCWs), NLUSERLANG and NLDATALANG, permit the
subsystem user to designate a default language other than NATIVE-3000 for
the subsystems.  Each of the five subsystem programs (SORT, MERGE, FCOPY,
QUERY, and ENTRY) looks at one of these JCWs, and its value is used as a
default language by the program.  The default can be superseded by a
specific command.
