                         |          |     |          |
                         +----------+     +----------+

         The  GOLD_G  key moves the cursor to the position previously
         saved with a GOLD_M key.   GOLD_G can't move between buffers
         and/or windows.

         Eight different positions can be specified to the GOLD_G key
         by using the EDT repeat count facility.  To specify position
         2 for example, you would use the key sequence:

                                 GOLD 2 GOLD G

         If a repeat count is not specified, then position 1 is used.

           The GOLD_J  key substitutes one string for another in the
           select range.     GOLD_J will prompt for the two strings,
           and uses the responses from the last GOLD_J invocation as
           the defaults.
2 GOLD_L
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    L     |
                         |          |     |          |
                         +----------+     +----------+

                         |   GOLD   |  +  |    M     |
                         |          |     |          |
                         +----------+     +----------+

         The  GOLD_M  key saves (marks)  the current cursor position.
         The  GOLD_G  key can then be used to move the cursor back to
         this position.

         Eight different positions can be specified to the GOLD_M key
         by using the EDT repeat count facility.  To specify position
         2 for example, you would use the key sequence:

                                 GOLD 2 GOLD M

         If a repeat count is not specified, then position 1 is used.
2 GOLD_O
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    O     |

                         +----------+     +----------+

           The GOLD_Q  key is used to display the current line number
           along with the total number of lines in the buffer and the
           current cursor column position.
2 GOLD_R
                         +----------+     +----------+
                         |          |     |          |

                         +----------+     +----------+

         The GOLD_U key is used to set the case of selected text to be
         all upper or all lower case.     GOLD_U will prompt for Upper
         or Lower case.   You should enter either U or L.  The default
         case is lower case.
2 GOLD_UP
                         +----------+     +----------+

        EDT Emulator is displayed using the GOLD V keys.
2 GOLD_W
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    W     |
                         |          |     |          |
                         +----------+     +----------+

        The GOLD_W key is used to adjust the size of the windows when
        two windows are used.  GOLD_W prompts for the number of lines
        to adjust the windows by.     A positive number will increase
        the size of the main window by 4  lines and decrease the size
        of the reference window by 4 lines.
2 GOLD_X
                         +----------+     +----------+
                         |          |     |          |

                         +----------+     +----------+

          The definition of a  word  can be toggled between whitespace,
          non-alphanumeric characters, and if defined, a user specified
          word definition.    For information on  user  specified  word
          definitions, see help on Init_files.   The default setting is
          for words to be defined as non-alphanumerics.
2 GOLD_Y
                         +----------+     +----------+
                         |          |     |          |

                         |          |     |          |
                         +----------+     +----------+

        The GOLD_Y key will toggle the translation of escape sequences.
        This key should be used carefully,  because the cursor position
        may not  necessarily  correspond  with the true position in the
        text buffer.    Also, escape sequences sent to the terminal may
        interfere with those normally sent by the screen manager.   Use
        this key at your own risk.
2 GOLD_Z
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    Z     |
                         |          |     |          |
                         +----------+     +----------+

        Displays the contents of the message buffer.   Carriage returns
        and line feeds are processed to allow system shutdown and other
        messages to be read.
2 GOLD_$
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    $     |
                         |          |     |          |
                         +----------+     +----------+

         The GOLD_$ creates a subprocess to execute DCL commands, and
         displays the output from the commands in the top window of a
         split screen display.   Information in the DCL buffer can be
         edited.

         The following restrictions apply:

          - This command can not be used in a CAPTIVE account or if
            your subprocess quota is exhausted.

          - You do not see any prompts from utilites

          - Only utilities which support input/output to a mailbox
            may be used.   Utilities such as PHONE or TPU which take
            full control of the screen will not work properly.
2 GOLD_<
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    <     |
                         |          |     |          |
                         +----------+     +----------+

          The GOLD_< key sets the left margin to be used when margin
          support is enabled.
2 GOLD_>
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    >     |
                         |          |     |          |
                         +----------+     +----------+

          The GOLD_< key sets the right margin to be used when margin
          support is enabled.
2 GOLD_TAB
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |   TAB    |
                         |          |     |          |
                         +----------+     +----------+

          The GOLD_TAB key prompts for a new spacing between tab stops.
          If a spacing of 0 is specified, the TAB key reverts to normal
          EDT TAB functionality.
2 Box_Cut_Paste
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    B     |
                         |          |     |          |
                         +----------+     +----------+

        The GOLD_B key will toggle the definition of  the  CUT (Remove),
        PASTE (Insert here), and SELECT keys between the normal EDT mode
        and box mode.

        In box mode,  the select key will create a marker for one corner
        of an imaginary box on the screen.   The opposite corner is def-
        ined by the position of the cursor.  The box defined by the mar-
        ker and the cursor is used by the CUT key.

        In box mode, all of the text which is inside the box will be CUT
        out, and replaced by spaces.   For a PASTE, the box in the paste
        buffer will overlay any text when in it pasted in.    The cursor
        is used to mark the upper left corner of a PASTE box.

                                   EXAMPLE:

                               ................
                               ....M...........
        BOX SELECTED           ................     M - Marker
          BEFORE CUT:          ...........C....     C - Cursor
                               ................


                               ................
                               ....C       ....

          BEFORE PASTE         ....        ....
                               ......C.........


                               ................
                               ....        ....
        AFTER PASTE            ....        ....     C - Cursor
                               ....        ....
                               ......C.........
                                     ........
                                     ........
2 Center_Line
                         +----------+     +----------+

                         |   GOLD   |  +  |    C     |
                         |          |     |          |
                         +----------+     +----------+

           The GOLD_C key will center the text on the current line.
2 DCL
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    $     |
                         |          |     |          |
                         +----------+     +----------+

         The GOLD_$ creates a subprocess to execute DCL commands, and
         displays the output from the commands in the top window of a
         split screen display.   Information in the DCL buffer can be
         edited.

         The following restrictions apply:

          - This command can not be used in a CAPTIVE account or if
            your subprocess quota is exhausted.

          - You do not see any prompts from utilites

          - Only utilities which support input/output to a mailbox
            may be used.   Utilities such as PHONE or TPU which take
            full control of the screen will not work properly.
2 Enter_CTRL_Char
                            +----------+----------+
                            |          |          |
                            |   CTRL   |    V     |
                            |          |          |
                            +----------+----------+

          The Control/V key will place the next character, including
          control characters at the current cursor position.    This
          provides,  for example,  a convienent  way to enter escape
          sequences by typing CTRL/V <ESC> (CTRL/V CTRL/[ on VT220).
2 Graphics/Escape_Seq
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    Y     |
                         |          |     |          |
                         +----------+     +----------+

        The GOLD_Y key will toggle the translation of escape sequences.
        This key should be used carefully,  because the cursor position
        may not  necessarily  correspond  with the true position in the
        text buffer.    Also, escape sequences sent to the terminal may
        interfere with those normally sent by the screen manager.   Use
        this key at your own risk.
2 Goto_Line
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    L     |
                         |          |     |          |
                         +----------+     +----------+

         The GOLD_L key will prompt for a line to move the cursor to.
2 Init_File
  The Schlumberger EDT Emulator (APLTPU) can be customized to
  suit your needs with initialization files.     Two types of
  initialization files may be used,  COMMAND files containing
  VAXTPU commands, and INITIALIZATION files containing APLTPU
  commands.
3 COMMAND_files
  Command files contain VAXTPU commands and are documented in the
  VAX Text Processing Utility Manual in the VMS documentation set.
  The search sequence for command files is:

  1) None if /NOCOMMAND is specified in the TPU command line

  2) Any file specified by /COMMAND in the TPU command line

  3) Under VMS V4.x, the logical name TPUINI is used next
     Under VMS V5.x, the logical name TPU$COMMAND is used next

  4) Under VMS V4.x, the file TPUINI.TPU in the current directory
     Under VMS V5.x, the file TPU$COMMAND.TPU in the current directory

3 INITIALIZATION_files
  Initialization files contain  Schlumberger  EDT Emulator (APLTPU)
  commands to  allow  you to  change the  default setting of APLTPU
  options.

  APLTPU commands can be abbreviated to the shortest unique command.
4 File_names
  The search sequence for initialization files is:

  1) (VMS V5.x) None if /NOINIT is specified in the TPU command line

  2) (VMS V5.X) Any file specified by /INIT in the TPU command line

  3) The logical name APLTPU$INIT.APLTPU

  4) The file APLTPU$INIT.APLTPU in the current directory

  5) The file APLTPU$INIT.APLTPU in your login directory, SYS$LOGIN:
4 Comments
        ! Comment

  Lines in an APLTPU$INIT file beginning with "!" are treated as
  comments and ignored.
4 Continuation
  APLTPU commands may be continued to another line by ending them
  with a "-".
4 ENABLE_BOX
        {ENABLE|DISBALE} BOX

  The ENABLE/DISABLE BOX command performs the same function as the
  GOLD B command and changes the  SELECT/CUT/PASTE keys to work in
  either BOX mode or the normal EDT mode.      See GOLD_B for more
  information.
4 ENABLE_DISPLAY
        {ENABLE|DISBALE} DISPLAY option

  The ENABLE/DISABLE DISPLAY commands affect the display from
  APLTPU commands.   Currently,  the only supported option is

        {ENABLE|DISBALE} DISPLAY DEFAULT_FILENAME

  which affects the  display  of  a default file name for the
  GOLD CTRL/B key.  GOLD CTRL/B will still use a default file
  name of the last file specified to  GOLD CTRL/B,  but won't
  show the default file name in the prompt when disabled.
4 ENABLE_MARGIN
        {ENABLE|DISBALE} MARGIN

  The ENABLE/DISABLE MARGIN  command performs the same function
  as the GOLD F key and enables margin support,    causing text
  to stay within the bounds specified by either SET LEFT_MARGIN
  and SET RIGHT_MARGIN or by the GOLD_< and GOLD_> keys.
4 HELP
        HELP

  HELP may be entered as an interactive initialization command
  to obtain help on initialization commands.  It is ignored in
  APLTPU$INIT files.
4 MESSAGE

        MESSAGE message

  The message command will display the specified message in the
  message window.
4 SET_CURSOR
        SET CURSOR top:bottom

  Controls scrolling of the screen relative to the distance of the
  cursor from the screen top and the screen bottom.  Values for the
  top and bottom can range from 0 to 21.  Default:  SET CURSOR 7:14.
4 SET_DCL
        SET DCL {ERASE|NOERASE}

  Controls whether the DCL command erases the DCL buffer between
  DCL commands.
4 SET_INSERT
        SET INSERT

  Sets the MAIN buffer to be in insert mode whereby text is inserted
  at the cursor position as it is entered.
4 SET_LEFT_MARGIN
        SET LEFT_MARGIN n

  The SET LEFT_MARGIN command performs the same function as the
  GOLD_< key and sets the left margin  to  column  n  if margin
  support is enabled (GOLD_F or ENABLE MARGINS)
4 SET_OVERSTRIKE
        SET OVERSTRIKE

  Sets the MAIN buffer to be in overstrike mode whereby text is
  replaced at the cursor position as it is entered.
4 SET_QUIET
        SET QUIET

  The SET QUIET command will turn off command verification until
  a SET VERIFY command is issued.    This will eliminate some of
  the messages from APLTPU commands.
4 SET_RIGHT_MARGIN
        SET RIGHT_MARGIN n

  The SET RIGHT_MARGIN command performs the same function as the
  GOLD_> key and sets the right margin  to  column  n  if margin
  support is enabled (GOLD_F or ENABLE MARGINS)
4 SET_SCREEN
        SET SCREEN width

  Sets the maximum number of characters that VAXTPU displays on
  a line of text.  The possible widths for VT100 terminals with
  advanced video option  (AVO)  are 80 and 132.   The width for
  VT100 terminals without AVO is 80.    The possible widths for
  VT200 terminals are 80 and 132.    Default:  set by operating
  system.
4 SET_SEARCH
        SET SEARCH {GENERAL|EXACT}

  If EXACT,  then the case of the characters must be the same.

        SET SEARCH {BEGIN|END}

  If END,  then the current position will become the character
  following the located string; otherwise it will be the first
  character of the located string (default).
4 SET_TAB
        SET TAB EDT number

  SET TAB EDT is equivelent to EDT line mode SET TAB command
  to set the tab value for tabbing functions.


        SET TAB EVERY number

  The SET TAB EVERY will change the "size" of the tab key to
  be every "number" spaces.
4 SET_VERIFY
        SET VERIFY

  The SET VERIFY command will turn on command verification
  previously turned off by SET QUIET.
4 SET_WORD
        SET WORD {EDT|NON-ALPHANUMERIC|"user specified"}

  The  SET WORD  command performs the same operation as the GOLD_X key
  and changes word delimiters to be whitespace (EDT), non-alphanumeric
  characters (NON-ALPHANUMERIC), or any user specified delimeters.
4 SET_WRAP
        SET WRAP number

  Determines the column (when margin support is disabled) at which
  text will be wrapped when in keypad mode.   It is also the right
  margin used by the FILL command.     If a SET WRAP number is not
  issued, then the FILL command uses the window size.
4 TPU
        TPU command

  Executes the specified VAXTPU command.
2 Input_File
        The Schlumberger EDT Emulator (APLTPU) is invoked as follows:

                $ TPU filename [,filename [,...]]

        The filename can contain wildcards.   Note that the symbols
        TPU and TPUR should be defined as follows:

                $ TPU  :== @SYS$LIBRARY:APLTPU
                $ TPUR :== @SYS$LIBRARY:APLTPUR

        TPUR will edit files /READ_ONLY, and will not use a journal
        file.
3 /CONFIRM
        The /CONFIRM switch causes APLTPU to confirm for each file
        to be edited,  whether  or not the file should actually be
        edited.  You can answer Yes, No, or Quit.   The default is
        not to edit the file.     Quit will cause  APLTPU  to stop
        searching for files.

        Example:

            $ TPU *.COM/CONFIRM
            Edit file SYS$SYSDEVICE:[USER]BINREAD.COM;4 [Y/N/Q]?
            Edit file SYS$SYSDEVICE:[USER]LOGIN.COM;132 [Y/N/Q]?
            Edit file SYS$SYSDEVICE:[USER]SEARCH.COM;1 [Y/N/Q]? Q
            $
2 Insert/Overstrike
                         +----------+     +----------+
                         |          |     |          |
                         |   GOLD   |  +  |    O     |
                         |          |     |          |
                         +----------+     +----------+

          The GOLD_O key toggles between insert and overstrike modes
          for the current buffer.
2 Learn
        The Schlumberger EDT Emulator can  "learn"  a function.   This
        is similar to the define key feature of EDT.  A learn sequence
        is started by using the CTRL/K key.   You will be prompted for
        a key to define.   After you hit the key to be defined, all of
        the keystrokes  you enter will be remembered unitl a CTRL/R is
        entered.    The next time that you use the  newly defined key,
        the keystrokes for the key will be performed again.  Note that
        if the  definition  includes  any keys which prompt for input,
        the answer you provided in learn mode is used.

                        CTRL/K - Begin learn sequence
                        CTRL/R - End learn sequence
2 Line/Column

                         |          |     |          |
                         +----------+     +----------+

        The GOLD_F key toggles margin support ON/OFF.   If margin support
        is enabled, then the space, tab, return, and fill keys will cause
        text to be formatted within the margins specified by  the  GOLD_<
        and GOLD_> keys (columns 1 and 75 by default).

        EDT Emulator is displayed using the GOLD V keys.
2 Windows
       The Schlumberger Extended EDT Emulator allows editting in either
       one or two windows. When two windows are used, the bottom window
       is mapped to the main buffer with the file that is being edited,
       and the top window mapped either to a reference file or  to  the
       main buffer. All editing operations are allowed in both windows.
       The following keys are used to manipulate windows:

              CTRL/B       - Toggle between one and two windows
              GOLD CTRL/B  - Open a reference file in top window
              GOLD UP      - Move to top window

          The definition of a  word  can be toggled between whitespace,
          non-alphanumeric characters, and if defined, a user specified
          word definition.    For information on  user  specified  word
          definitions, see help on Init_files.   The default setting is
          for words to be defined as non-alphanumerics.
1 EDT_EMULATOR
 The EDT Keypad Emulator is an interactive text editor that
 demonstrates the versatility and extensibility of the VAXTPU
 programming language.  This editor emulates the keypad functions
 and some of the line mode commands of the EDT Version 3 text
 editor.  The purpose of the EDT Keypad Emulator is to provide you
 with a familiar editing interface.  It is hoped that you will use
 this editor as you have used EDT, but then go on to enhance the
 editor with the further powerful capabilities of the VAXTPU
 language.
2 HELP
 To use help from the CTRL/Z, '*' prompt, type HELP followed by a
 line_mode_command.  If the cursor is positioned after the 'Topic?'
 prompt then type:

    EDT                - to get a list of EDT_EMULATOR topics

    EDT LINE           - to get a list of line mode commands

    EDT KEY            - to get a list of keypad commands

    EDT VAXTPU_EQU     - to get help on VAXTPU syntax for missing
                         line mode commands
2 KEYPAD_FUNCTIONS

 One major difference between EDT and the VAXTPU EDT Keypad
 Emulator is the use of GOLD Keypad 7 (PF1 and KP7).  This command

 included for that key.

2 LINE_MODE_COMMANDS

 The EDT Keypad Emulator provided with VAXTPU emulates only a few
 of the line mode commands offered by EDT.  To enter one of the
 line mode commands, press CTRL/Z.  The asterisk prompt (*) appears
 at the lower left margin of your screen.  Enter the EDT Keypad
 Emulator line mode command followed by RETURN.  To reenter keypad
 mode, type the letter C, for Change, followed by RETURN.  The
 cursor returns to its former location in the text.

 You can extend or enhance the EDT Keypad Emulator's line mode
 commands by using the VAXTPU programming language.  See the VAX
 Text Processing Utility Reference Manual for more information on
 customizing the VAXTPU EDT Keypad Emulator editing interface.

3 CHANGE

 C

 Shifts the EDT Keypad Emulator to keypad mode, and returns the
 cursor to its former location in the text.

3 EXIT
 EXIT [/SAVE] [file-spec]

 Ends the EDT Keypad Emulator session, saving a copy of the
 MAIN_BUFFER text in an external file.

4 /SAVE

 The /SAVE command line qualifier tells the EDT Keypad Emulator to
 save the journal file.  Whenever you use /SAVE, you must type a
 slash before it to signal the emulator that the following letters
 refer to a qualifier, and not a command word or string.  The /SAVE
 qualifier must be placed before the file name in this command.

3 INCLUDE

 INCLUDE file-spec [=buffer]

 Copies the specified file into the current EDT Keypad Emulator
 session, at the current cursor position.  If you supply a buffer
 specification, it becomes the new current buffer.

3 QUIT
 QUIT [/SAVE]

 Ends your editing session without saving a copy of your editing
 work.  The EDT Keypad Emulator prompts you with the message:
 'Buffer modifications will not be saved, continue quitting (Y or
 N)?' only if you modified the text.  You respond with a Y or N.
4 /SAVE

 The /SAVE command line qualifier tells the EDT Keypad Emulator to
 save the journal file.  Whenever you use /SAVE, you must type a
 slash before it to signal the emulator that the following letters
 refer to a qualifier, and not a command word or string.  The /SAVE
 qualifier is the last element in the command line.
3 SUBSTITUTE

 SUB /old_string/new_string/ [WHOLE]

 Replaces old_string with new_string.  If you supply no location
 specifiers, the substitution takes place at the first occurrence
 of "old_string" on the current line.  If you specify WHOLE, then
 the substitution is made throughout the current buffer.

3 WRITE

 WRITE file-spec [select|whole]

 Puts a copy of the entire current buffer or select range into the
 specified file.  Unlike EXIT, this command does not end the
 current editing session.  The SELECT option allows you to copy a
 selected region of text into the specified file.  When finished
 copying the text, the select range is reset.

3 SET

 SET commands allow you to customize your editing session.

4 CURSOR

 SET CURSOR top:bottom

 Controls scrolling of the screen relative to the distance of the
 cursor from the screen top and the screen bottom.  Values for the
 top and bottom can range from 0 to 21.  Default:  SET CURSOR 7:14.
4 SCREEN

 SET SCREEN width

 Sets the maximum number of characters that VAXTPU displays on a
 line of text.  The possible widths for VT100 terminals with
 advanced video option (AVO) are 80 and 132.  The width for VT100
 terminals without AVO is 80.  The possible widths for VT200
 terminals are 80 and 132.  Default:  set by operating system.
4 SEARCH
 SET SEARCH {GENERAL|EXACT}

 If EXACT, then the case of the characters must be the same.

 SET SEARCH {BEGIN|END}

 If END, then the current position will become the character
 following the located string; otherwise it will be the first
 character of the located string (default).
4 TAB

 SET TAB number

 Sets the tab value for various tabbing functions.

4 WRAP

 SET WRAP number

 Determines after which character VAXTPU wraps text being inserted
 in keypad mode.  It is also the right margin used in the FILL
 command.  If a SET WRAP number is not indicated, then the FILL
 command uses the current window size as the right margin.

3 SHOW

 SHOW commands tell which SET commands are in effect.

4 BUFFER

 Lists all buffers currently in use during your EDT Keypad Emulator
 session.  Also lists the number of lines in each buffer and the
 file name.  An equal sign (=) indicates the current buffer.

4 CURSOR

 Shows where scrolling of the screen relative to the distance of
 the cursor from the screen top and the screen bottom occurs.
 Values for the top and bottom can range from 0 to 21.  Default:
 SET CURSOR 7:14.

4 SCREEN

 Shows the maximum number of characters that VAXTPU displays on a
 line of text.  The possible widths for VT100 terminals with
 advanced video option (AVO) are 80 and 132.  The width for VT100
 terminals without AVO is 80.  The possible widths for VT200
 terminals are 80 and 132.  Default:  set by operating system.

4 SEARCH

 Shows how VAXTPU performs searches.  Default:  SET SEARCH GENERAL,
 SET SEARCH BEGIN.

4 VERSION

 Displays the current VAXTPU version number and the current version
 number of EDTSECINI.TPU (the EDT Keypad Emulator section file).

4 WRAP

 Shows after which character VAXTPU wraps text being inserted in
 keypad mode.  It is also the right margin used in the FILL
 command.  If a SET WRAP number is not indicated, then the fill
 command uses the current window size as the right margin.

3 Command_line_specifiers

4 buffer

 The name of a VAXTPU buffer.  Use the equal sign (=) immediately
 before the buffer name (for example, =MAIN).  If the buffer does
 not exist, VAXTPU creates one.  The EDT Keypad Emulator moves to
 the named buffer, except in the case of the WRITE command.

4 file-specification

 The specification for an external file.  It can include a
 directory specification.  With INCLUDE, it tells the EDT Keypad
 Emulator which file to copy into your editing session.  With EXIT
 and WRITE, it tells the EDT Keypad Emulator which file to create
 to hold text from your editing session.  If you include directory
 information, the directory must exist and you must have access to
 it.

4 select

 A selected region of text.  The selected text is copied into a
 file that is specified in the WRITE command.

4 whole

 The entire buffer is used.  With WRITE, it tells VAXTPU to write
 out the entire buffer (default).  With the SUBSTITUTE command, it
 tells VAXTPU to search the entire buffer.

3 Missing_commands

 Although the EDT Keypad Emulator provides only a few of the most
 frequently used line mode commands, missing commands can be
 executed by using VAXTPU built-ins from the Gold KP7 command line.
 To get a list of the VAXTPU syntax for the missing EDT line mode
 commands, ask for help on EDT_EMULATOR VAXTPU_EQUIVALENTS.

2 VAXTPU_EQUIVALENTS
    The following table gives a quick view of how to enter VAXTPU
