Scrolls a display's screen window in a specified  direction  over
     the  text of the display.  This makes additional display contents
     visible.  Unless the display to be scrolled is explicitly  named,
     the current scrolling display, as selected with a previous SELECT
     command, is scrolled.

     Note the use of keypad keys KP8, KP2, KP4 and KP6 for  scrolling.
     Also note that you can use keypad key KP3 to rotate the scrolling
     attribute around the various displays.

 Format:

     SCROLL/qualifier [disp-name]

 Examples:

     DBG> SCROLL/UP       ! Scroll up "--scroll--" display
     DBG> SCROLL/UP OUT   ! Scroll up OUT display
     DBG> SCROLL/UP:1 OUT ! Scroll up OUT display by only 1 line

     command, is scrolled.

/BOTTOM/DOWN/LEFT/RIGHT/SUFFIX/UP/TOP

     Scroll down to the bottom of the display's text.

     Scroll down through the display text by n lines  to  reveal  text
     further  down  in  the  display.  If n is omitted, the display is
     scrolled by approximately 3/4 of its window height.

     Scroll left over the display text by n  columns  to  reveal  text
     beyond  the  left margin.  You cannot scroll past column 1.  If n
     is omitted, the display is scrolled left by 8 columns.

     Scroll right over the display text by n columns  to  reveal  text
     beyond  the right margin.  You cannot scroll past column 132.  If
     n is omitted, the display is scrolled right by 8 columns.

     Note:   This  qualifier  applies  to  a  multiprocess   debugging
     configuration (when DBG$PROCESS has the value MULTIPROCESS).  Use
     this qualifier only directly after a display name.

     Appends a process-identifying suffix  to  a  display  name.   The
     suffix  denotes  the  visible  process.   This  qualifier is used
     primarily  in  command   procedures   when   specifying   display
     definitions   or  key  definitions  that  are  bound  to  display
     definitions.  Use any of  the  following  process-identifier-type
     keywords:

        PROCESS_NAME     The display-name suffix is the VMS process name.

        PROCESS_NUMBER   The display-name suffix is the process number
                         (as shown in a SHOW PROCESS display).

        PROCESS_PID      The display-name suffix is the VMS process
                         identification number (PID).

     If  you  specify  /SUFFIX  without  a  process-identifier-   type
     keyword,  the  process  identifier type used for the display-name
     suffix is, by default, the same  as  that  used  for  the  prompt
     suffix (see SET PROMPT/SUFFIX).

     Scroll up through the display text by  n  lines  to  reveal  text
     further  up  in  the  display.   If  n is omitted, the display is
     scrolled by approximately 3/4 of its window height.

     Scroll up to the top of the display's text.
