The SET command is used to change several options including:

         The characteristics of a particular field.
         The automatic positioning of windows.
         The function of the arrow keys.
         The number of seconds between display updates.
         The number of columns used by the display.

  Format:  SET option

1  –  Field

  Changes the characteristics of a particular field.

  Format:  SET field-name[,...] [/qualifier,...]

  NOTE: For a complete list of field names, type HELP FIELDS from the
        command prompt. If the list of fields scrolls off your terminal,
        enter SET SCREEN=132 or refer to the OpenVMS System Management
        Utilities Reference Manual. For a list of field names in a
        particular class, type HELP CLASSES class-name from the command prompt.

1.1  –  Qualifiers

1.1.1    /FORMAT

  Sets the radix to be used to display a particular field.  FORMAT
  applies only to decimal and hexadecimal fields.  Ascii fields can
  not be changed.

  Format:  SET field-name[,...] /FORMAT=radix [/qualifier,...]

  Note:  The HW_VERS field can be displayed in hexidecimal only.

1.1.2    /WIDTH

  Sets the number of columns to use to display a particular field.
  Specifying a value less than the minimum allowed for a particular
  field will set the number of columns for that field to the minimum
  value.  Specifying a value greater than the maximum number of
  columns allowed for a particular field will set the number of
  columns for that field to the maximum value.

  Format:  SET field-name[,...] /WIDTH=value [/qualifier,...]

2  –  AUTO_POSITIONING

  Enables or disables automatic positioning of windows on the screen.
  By default, AUTO_POSITIONING is ON and windows are automatically
  positioned based on their size and the order in which they were added.
  Windows will be positioned so that they do not overlap, but they can
  extend, fully or in part, beyond the physical limits of the screen.
  Attempting to MOVE a window sets AUTO_POSITIONING to OFF and allows
  windows to be positioned manually. To reposition a window, you must
  first SELECT the window to be moved if more than one window is
  being displayed and then MOVE the window to its new position.  When
  you position windows manually, windows are allowed to overlap. For more
  information on moving windows manually, see help on SELECT and MOVE.

  Format:  SET AUTO_POSITIONING ON
           SET AUTO_POSITIONING OFF

  Note:  The SET FUNCTION MOVE command and the MOVE command
         implicitly set auto-positioning to off.

3  –  FUNCTION

  By default, the arrow keys function as editing keys to provide command
  line recall and line editing.  The SET FUNCTION command redefines the
  function of the arrow keys on the terminal to one of three additional
  functions: PAN, SCROLL or MOVE. For example, by entering the SET FUNCTION
  PAN command, the left arrow, right arrow, up arrow, and down arrow keys,
  are defined as PAN LEFT 1, PAN RIGHT 1, PAN UP 1, and PAN DOWN 1.

  The SET FUNCTION SCROLL and SET FUNCTION MOVE commands redefine the
  arrow keys in a similar manner.  Command line recall and line editing
  can be restored by entering the SET FUNCTION EDIT command.

  Format:  SET FUNCTION function-name

  Note: The SET FUNCTION MOVE command implicitly turns auto-positioning off.

4  –  INTERVAL

  Specifies the amount of time to wait between display updates
  expressed in seconds.  Using the SET INTERVAL commands overrides
  the /INTERVAL qualifier used at the DCL level.

  Format:

         SET INTERVAL = seconds

5  –  SCREEN

  Sets the maximum number of columns to be used by the display.
  Accepted range is 1 to 511.

  Note:  For certain types of terminals, character size is
         dependent on the number of columns per line and
         will change as the number of columns is increased
         or decreased.

  Format:  SET SCREEN = width
