SET RIGHT MARGIN

 Sets the right margin of the current buffer for entering or formatting
 text.  (By itself, it does not change existing text.)

 Example:

    Command                  Purpose or effects
    ---------------------------------------------------------------------
    1.  SET RIGHT MARGIN 70  Sets the right margin at column 70.  When EVE
                             wraps text, no lines go beyond column 70.

    2.  FILL PARAGRAPH       Reformats the current paragraph, wrapping text
                             at the right margin of the buffer.

 o  The right margin must be greater than the left margin.  The default
    right margin is one column less than the width.  Thus, if the width is
    80 columns, the default right margin is 79.  To find out the current
    margins of the buffer, use SHOW.

 o  At startup, SET RIGHT MARGIN in an initialization file affects both the
    main buffer and a system buffer named $DEFAULTS$.  Buffers created
    during the session will have the same margins as $DEFAULTS$.  See help
    on DEFAULTS.

 o  SET WIDTH makes the right margin of the $DEFAULTS$ buffer one column
    less than the width, but does not affect the margins of other, existing
    buffers.  See help on SET WIDTH.
