     Name       : LANGBLK
     Description: CMS Language Control Block
     DSECT      : LANGBLK
     Function   : Generates a copy of language control
                  block for the caller. LANGBLK points to
                  language information that an application uses.
                  The LANGBLK for the default language is in
                  DMSNUC. A LANGBLK is created by the set
                  language command. LANGBLK is called by the
                  LANGBLK macro.
