Library /sys$common/syshlp/lse$clihelp.hlb DEFINE, ADJUSTMENT, Qualifiers, /LANGUAGE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /LANGUAGE=language-name

    Specifies the language associated with the indentation adjustment.
    By default, the new adjustment is associated with the language for
    the current buffer. If there is no language associated with the
    current buffer, then the /LANGUAGE qualifier is required.
