VMS Help RTL Routines, LIB$, LIB$ENABLE_CTRL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Enable CLI Interception of Control Characters routine
    requests the calling process's command language interpreter
    (CLI) to resume interception of the selected control characters
    when they are typed during an interactive terminal session.
    LIB$ENABLE_CTRL provides the same function as the DCL command
    SET CONTROL.

    Format

      LIB$ENABLE_CTRL  enable-mask [,old-mask]
