APERTURE:
Command syntax: SET APERTURE [aperture-width]

    Set the aperture in inches for GIN pick event. Default aperture=0.1 
    inches; Max aperture=1.0 inches. The aperture means how close GIN 
    crosshair cursor has to be positioned to a layout entry in order 
    to pick it. Issue this command before getting into GIN mode if 
    you desire a different aperture from the default.
    Example: LAYOUT> SET APERTURE 0.2


BLINK:
Command syntax: SET BLINK

    Flip the highlighting feature (blink) for the pick event. 
    The default status is blink-on upon picked.


CHORD:
Command syntax: SET CHORD [angle]

    Set the chord angle for drawing ARC, where the angle is specified
    in degrees and the valid angle range is from 0.5 to 15.0 degrees. 
    The default chord is 10.0 degrees.
    Example: LAYOUT> SET CHORD 5.0


DALINE:
Command syntax: SET DALINE [nline]

    Set dialog area lines to that designated by "nline".
    The valid number of lines are from 0 to 30.
    If nline<2, dialogue area is invisible.
    Example: LAYOUT> SET DALINE 15


FKEYS:
Command syntax: SET FKEYS

    Flip function keys F1,F2,...,F8 between defined and undefined.
    Enter "HELP FKEYS" to see the definitions of the function keys.


FRAME:
Command syntax: SET FRAME

    Flip background frame between visible and invisible.


HARDCOPY:
Command syntax: SET HARDCOPY on/off

    Enable (ON) or disable (OFF) preparation of device independent
    (DI) file for hardcopy. Whenever you plot a new layout file or 
    clear the screen, flag ON is set so that you can invoke hardcopy
    making if desired. Under following circumstances you may want
    to suppress writing the DI file:

     	[1] You don't intend to make a hardcopy during this layout
     	    session so that you save a bit of memory and CPU.
     	[2] In the process of building a layout involving layout
     	    editing or layout transform because the DI file is a
     	    "one-way-valve" file. To make a hardcopy from such a
     	    layout session, save what you have built into a file,
     	    replot the file and then invoke the hardcopy.


LINE:
Command syntax: SET LINE [line-type,line-width]

    Set active line-type and line-width for subsequent drawing of
    new layout entries. The defaults are 1,1.


ORIGIN:
Command syntax: SET ORIGIN [px,py]

    Set the working origin of layout at (px,py) relative to the graph 
    origin and (px,py) is specified in inches. By default the working
    origin is the same as the graph origin. Drawing of new layout and
    and layout transform refer to the working origin but the layout 
    stored in the layout file refers to the graph origin.
    Example: LAYOUT> SET ORIGIN 1.5 2.5


SCALE:
Command syntax: SET SCALE [color-code,nx,mx,ny,my]

    Set a layout crosshair scale which helps cursor location, where

        color-code --- color of the scale [white]
        nx ---- number of major divisions along x-axis [10].
        mx ---- number of minor divisions between the majors [10].
        ny ---- number of major divisions along y-axis [10].
        my ---- number of minor divisions between the majors [10].

    If no parameter is given, the default scale is flipped and,
    when on, intersecting at the current working origin.
    Example: LAYOUT> SET SCALE red 9 10 7 10
