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

    The Disable CLI Interception of Control Characters routine
    requests the calling process's command language interpreter (CLI)
    to not intercept the selected control characters when they are
    entered during an interactive terminal session. LIB$DISABLE_CTRL
    provides the same function as the DCL command SET NOCONTROL.

    Format

      LIB$DISABLE_CTRL  disable-mask [,old-mask]
