1    /DYNAMIC

       /DYNAMIC
       /NODYNAMIC

    Controls whether a display automatically adjusts its window
    dimensions proportionally when a SET TERMINAL command is issued.
    /DYNAMIC is the default.

2    /HIDE

    /HIDE conceals the display under any other displays that overlap
    it. As a result, any displays that were previously hidden under
    the specified display become visible.

3    /POP

    /POP places a specified display at the top of the display
    pasteboard, ahead of any other displays. This is the default.

4    /PUSH

    Has the same effect as /HIDE.

5    /REMOVE

    Creates a display that does not appear on the screen. Although
    a removed display is not visible on the screen, its definition
    still exists, and you can request that it be displayed by using
    the DISPLAY command.

6    /SIZE

       /SIZE:n

    Sets the maximum size of a normal output display to be n lines.
    If more than n lines are written to the display, the oldest lines
    are lost as the new lines are added. If you omit this qualifier,
    the maximum size is set to 50 lines.

    For plot displays, n specifies the number of lines of PLOT or
    TABULATE output to be buffered internally by the Analyzer at one
    time. There is usually no need to change this number.
