LSE provides the following commands for manipulating buffers:

       CHANGE DIRECTION
           Alters the direction of the current buffer. This command is
           bound to Key F11 (PF3 in EVE VT100).

       CHANGE TEXT_ENTRY_MODE
           Alters the text entry mode of the current buffer between
           insert and overstrike. This command is bound to Key F14
           (ENTER in EVE VT100).

       COMPILE
           compiles the source code in the buffers.

       CUT [/BUFFER=name]
           deletes and moves text in the select range to the paste or
           specified buffer.

       DO [/BUFFER=name]
           directs LSE to execute LSE commands or VAXTPU
           program statements from the current or specified buffer.

       EXIT
           terminates an editing session and saves all modified buffers.

       EXTEND
           compiles one or more VAXTPU procedures to extend LSE.

       GOTO FILE file-spec
           moves to the buffer containing the specified file or creates
           a new buffer for the file.

       GOTO BUFFER name
           moves the cursor to the last position held in the specified
           buffer.

       GOTO SOURCE
           moves to the source buffer related to the diagnostic or query
           item. This command is bound to CTRL/G.

       PASTE [/BUFFER=name]
           copies the content of the paste or specified buffer to the
           current buffer.

       QUIT
           terminates an editing session without saving any modified
           buffers.

       READ file-spec [buffer]
           inputs a specified file to the current or specified buffer.

       SET AUTO_ERASE
           enables automatic erasing of placeholders.

       SET FORWARD [/BUFFER=name]
           sets the direction of the current or specified buffer forward.
           This command is bound to Keypad 4 (no binding for EVE VT100).

       SET INDENTATION [/BUFFER=name]
           changes the indentation level for the current or specified
           buffer.

       SET INSERT [/BUFFER=name]
           sets the text entry mode of the current or specified buffer
           to insert mode.

       SET LANGUAGE [/BUFFER=name]
           changes the language associated with the current or specified
           buffer.

       SET LEFT_MARGIN [/BUFFER=name]
           specifies the left margin for the buffer for FILL and ENTER
           space commands.

       SET MODIFY [/BUFFER=name]
           sets buffer status to modifiable.

       SET NOAUTO_ERASE
           disables automatic erasing of placeholders.

       SET NOMODIFY
           sets buffer to unmodifiable.

       SET NOWRAP
           disables wrapping in the indicated buffer.

       SET OUTPUT_FILE [/BUFFER=name]
           changes the output file associated with the current or the
           specified buffer.

       SET OVERSTRIKE [/BUFFER=name]
           sets the text entry of the current or specified buffer to
           overstrike mode.

       SET REVERSE [/BUFFER=name]
           sets the direction of the current or specified buffer to
           reverse. This command is bound to Keypad 5 (no binding for
           EVE VT100).

       SET RIGHT_MARGIN [/BUFFER=name]
           specifies the right margin for the buffer for FILL and ENTER
           space commands.

       SET TAB_INCREMENT [/BUFFER=name]
           specifies the number of columns between tab stops for the
           current or specified buffer.

       SET WRAP
           enables wrapping in the indicated buffer.

       SET WRITE [/BUFFER=name]
           specifies that following a COMPILE command or an exit from
           LSE, the specified buffer will be written to a file.

       SHOW BUFFER [name | *]
           displays the characteristics of a specified or default buffer.

       WRITE [/BUFFER=name] [file]
           outputs the content of the current or specified buffer to
           to a specified file.
