1  EXPAND
   PCA Command

   Expands or contracts the window associated with a screen display.

   Format

     EXPAND  [disp-name[,...]]
 

2  Parameters
 

disp-name

   Specifies a display to be expanded or contracted. You may specify
   any of the following:

   o  A predefined display: SRC, OUT, PROMPT, PLOT

   o  A display previously created with the SET DISPLAY command

   o  A pseudo-display name: %CURDISP, %CURSCROLL, %NEXTDISP,
      %NEXTOUTPUT, %NEXTPLOT, %NEXTSCROLL, %NEXTSOURCE

   If you do not specify a display, the current scrolling display,
   as established by the SELECT/SCROLL command, is chosen.
 

2  Description
   The EXPAND command moves one or more display-window borders
   according to the qualifiers specified (/UP[:n], /DOWN[:n],
   RIGHT[:n], /LEFT[:n]).

   The EXPAND command does not affect the order of a display on
   the display pasteboard. Depending on the relative order of
   displays, the EXPAND command may cause the specified display to
   hide or uncover another display or be hidden by another display,
   partially or totally.

   Except for the PROMPT display, any display can be contracted to
   the point where it disappears (at which point it is marked as
   "removed"). It can then be expanded from that point. Contracting
   a display to the point where it disappears will cause it to
   lose any attributes that were selected for it. The PROMPT
   display cannot be contracted or expanded horizontally but can
   be contracted vertically to a height of two lines.

   A window border can be expanded only up to the edge of the
   screen. The left and top window borders cannot be expanded beyond
   the left and top edges of the display, respectively. The right
   border can be expanded up to 255 columns from the left display
   edge. The bottom border of a display can be expanded down only to
   the bottom edge of the plot's summary page display (to the end of
   the source module).

   You must specify at least one qualifier.
 

2  Qualifiers
 

/DOWN

      /DOWN[:n]

   Moves the bottom border of the display down by n lines (if n is
   positive) or up by n lines (if n is negative). If n is omitted,
   the border is moved down by one line.
 

/LEFT

      /LEFT[:n]

   Moves the left border of the display to the left by n lines (if n
   is positive) or to the right by n lines (if n is negative). If n
   is omitted, the border is moved to the left by one line.
 

/RIGHT

      /RIGHT[:n]

   Moves the right border of the display to the right by n lines (if
   n is positive) or to the left by n lines (if n is negative). If n
   is omitted, the border is moved to the right by one line.
 

/UP

      /UP[:n]

   Moves the top border of the display up by n lines (if n is
   positive) or down by n lines (if n is negative). If n is omitted,
   the border is moved up by one line.
