PENCIL

        [GREG1\]PENCIL [N] [/COLOUR C] [/DASHED D] [/WEIGHT W] [/DEFAULT]

    Selects  virtual  pen  N  and defines its attributes in terms of colour,
    dashed pattern and weight (thickness). Up to  16  pens  can  be  defined
    (0-15).  Most plotting commands use the current pen. The major exception
    is RGMAP (iso-contouring) which uses the pen  0  (solid  and  foreground
    color by default) and 15 (dotted and blue by default). Some commands al-
    so ignore the dashed patterns, in particular all labels and the BOX com-
    mand.
      - The dashed pattern D must be in range 1 to 8, 1 means solid lines.
      -  The  weight factor W must be a weight number or value. See subtopic
        /WEIGHT for details.
      - The colour index C is a color number or name. See  subtopic  /COLOUR
        for details.
    PENCIL N /DEFAULT reset default attributes to Pen number N.  PENCIL /DE-
    FAULT reset default attributes for all Pens, as defined at program  ini-
    tialization.
