Additional information available:

Parameter

keyword-list
   Indicates the modes to be set or reset. The mode keywords and
   their effects are as follows:

BELL=NONE
   Specifies which new messages should be accompanied by a
   warning bell character. By default, only broadcast messages are
   accompanied by a warning bell.

KEYPAD=EDT
   Specifies whether the key definitions should be similar to EDT or
   EVE. Note that EVE key definitions do not use the numeric keypad
   on VT200 terminals; numeric keypads on VT200-series terminals
   emulate EDT key definitions regardless of the keypad mode you
   choose.

MENU=[NO]GRAPHICS
   Lets you choose between graphic characters and nongraphic
   characters in the display of a menu. The initial setting is
   MENU=GRAPHICS. If the terminal characteristics do not include
   DEC_CRT, then LSE uses nongraphic characters regardless of the
   setting of this mode.

   Graphic characters currently require more screen repainting
   than do nongraphic characters, so you may want to use SET MODE
   MENU=NOGRAPHICS if you are working at a low baud rate.

PENDING_DELETE
   Specifies whether a selection in a user buffer should be deleted
   when the user inserts text. The initial setting is NOPENDING_
   DELETE. PENDING_DELETE is disabled for a selection made with

   Sets specified characteristics of the screen.

   Format

     SET SCREEN   keyword-list

Additional information available:

Parameter

keyword-list
   Indicates the screen characteristics to be set. The screen
   keywords are as follows:

BALANCE_WINDOWS (D)
   Specifies how LSE manages window length. If you specify BALANCE_
   WINDOWS, LSE adjusts all the window lengths on the screen to
   be, as nearly as possible, of equal lengths. This is the default
   value. If you specify NOBALANCE_WINDOWS, LSE splits the current
   window in half when it needs a new window, leaving all the other
   window lengths unchanged.

HEIGHT=n
   Specifies the number of lines on the screen. The height, n, must
   be an integer in the range 11 through 62.

MAXIMUM_WINDOW_NUMBER=n
   Specifies the maximum number of windows LSE creates when it
   displays information in a window as a result of issuing one of
   the following commands:

      FIND
      GOTO DECLARATION
      GOTO SOURCE
      INSPECT
      REVIEW

   LSE uses the MAXIMUM_WINDOW_NUMBER and MINIMUM_WINDOW_LENGTH
   settings to determine whether to add a window to the screen or
   reuse an existing window. LSE checks both settings and creates a
   new window only if both conditions are met.

   The default value for MAXIMUM_WINDOW_NUMBER is 3. Specifying a
   value of 2 produces the two-window behavior previously associated
   with the commands listed under this keyword.

MINIMUM_WINDOW_LENGTH=n
   Specifies a lower bound on the windows LSE creates. When you need
   to map a buffer to a window, LSE creates a new window as long as
   the window is not shorter than n.

   LSE uses the MINIMUM_WINDOW_LENGTH and MAXIMUM_WINDOW_NUMBER
   settings to determine whether to add a window to the screen or
   reuse an existing window. LSE checks both settings and creates a
   new window only if both conditions are met.

WIDTH=n
   Specifies the number of characters on each input or output line.
   The width, n, must be an integer in the range 1 through 252.

   If you specify a width greater than 80, then LSE sets the terminal
   to 132-character mode. The initial setting is 80 characters.

WINDOW=n
   Specifies the number of windows to display on the screen.

   If you change the number of windows from one to two, LSE displays
   the current buffer in both windows. If you change the number of
   windows from two to one, LSE displays the current buffer in the
   single window. The initial setting is one window.

   Delimits the lines at which the cursor triggers scrolling.

   height, rounded to the nearest whole line count. This is useful
   when you have a workstation with screens of varying sizes.

   Sets text search options.

   Format

     SET SEARCH  keyword-list

Additional information available:

Parameter

keyword-list
   Indicates the search mode settings. The keywords are as follows:

   AUTO_REVERSE
   NOAUTO_REVERSE

   Specifies whether or not LSE searches in the current direction
   only, or searches in the opposite direction if the string is not
   found in the current direction. The initial setting is NOAUTO_
   REVERSE.

   CASE_SENSITIVE
   NOCASE_SENSITIVE

   Specifies whether or not the SEARCH command matches case exactly
   or is insensitive to character case. The initial setting is
   NOCASE_SENSITIVE.

   DIACRITICAL_SENSITIVE
   NODIACRITICAL_SENSITIVE

   Specifies whether or not the SEARCH command matches characters
   with diacritical markings exactly or is insensitive to diacritical
   markings. The initial setting is DIACRITICAL_SENSITIVE.

   PATTERN=VMS
   PATTERN=ULTRIX

   Specifies either ULTRIX-style regular expressions or VMS-style
   patterns for the SEARCH/PATTERN command. The initial setting is
   VMS.

   SPAN_SPACE
   NOSPAN_SPACE

   Determines whether LSE matches blanks in the search string exactly
   (NOSPAN_SPACE) or allows each blank to match sequences of one or
   more characters containing blanks and tabs and, at most, a single
   line break (SPAN_SPACE). The initial setting is NOSPAN_SPACE.

   not specify a directory-spec value, LSE adds the directory or
   directories to the end of the list.

   If you do not specify either the /AFTER qualifier or the /BEFORE
   qualifier, LSE replaces the entire directory list.

      /BEFORE
      /BEFORE[=directory-spec]

   Specifies that LSE should insert the directory or directories
   indicated into the list of source directories in front of the
   directory you specify as the value on the qualifier. If you do not
   specify a directory-spec value, the directory or directories are
   added at the front of the list.

   If you do not specify either the /BEFORE qualifier or the /AFTER
   qualifier, LSE replaces the entire directory list.

directory-spec [,directory-spec] ...
   Specifies one or more directory specifications. You can specify
   CMS$LIB as one directory specification; however, you may not get
   the results you expect if you set CMS$LIB as a source directory
   and do not issue the CMS command SET LIBRARY.
