    HEIGHT value specifies the maximum number of lines per page
    in your text output file. If you specify zero, the number of
    lines per page will correspond to the height specified in your
    document. If you also specify OVERRIDE_FORMAT, or if the document
    has no inherent page size, the document is formatted to the
    height value specified by this option. The default height is
    66 lines.
