VMS Help DSR, DSR Flags, Hyphenate  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    When the Hyphenate flag (=) is turned on and inserted between
    syllables of a word, DSR knows where the word can be broken at
    the end of a line. DSR inserts a hyphen where the break occurs.
    If DSR does not find it necessary to break the word, however,
    the hyphen does not appear. By default, the Hyphenate flag is
    disabled.

    The action of this flag (as opposed to the recognition of the
    flag) can be disabled or reenabled by the .DISABLE HYPHENATION
    and .ENABLE HYPHENATION commands.

1 - Default

    Recognition is turned off. To turn on recognition, you must use
    the .FLAGS HYPHENATE command.
