TECO invokes the TECO text editor.

Formats

 TECO file-spec                    to edit an existing file
 TECO out-file-spec=in-file-spec   to edit from one file to another
 MAKE file-spec                    to create a new file
 MUNG cmd-file-spec                to execute a TECO command file
 MUNG cmd-file-spec,text-arg       as above, but passes a text argument

As these are not built-in DCL commands, you need to enter

          TECO :== $SYS$SYSTEM:TECO TECO
          MAKE :== $SYS$SYSTEM:TECO MAKE
          MUNG :== $SYS$SYSTEM:TECO MUNG """

 in your LOGIN.COM file.  Please also read what HELP TECO INI says.
*Initialization
TECO decodes its commands with a built-in command decoder.  If TECO
 finds the logical name TEC$INIT, its equivalence string is assumed
 to be either a TECO macro or, if the string starts with a dollar
 sign ($), the rest of the string is assumed to be a file-spec
 containing a TECO macro to be executed every start up.  To disable
 the lookup of TEC$INIT, the qualifier /NOINI can be used.

Your LOGIN.COM file can define the TECO command with preset qualifiers
 if desired.  The qualifiers /NOCRE, /NOINI, and /NOMEM are recognized
 by all TECO commands so that they can be preset at command definition
 time.  To disable all TECO start up actions you would use

        TECO :== $SYS$SYSTEM:TECO TECO/NOCRE/NOINI/NOMEM

 To disable only TECO's memory you would use

        TECO :== $SYS$SYSTEM:TECO TECO/NOMEM

 Etc.
*Memory
TECO automatically remembers the file being edited.  The file's
 name is stored in a process logical called TEC$MEMORY.  If you
 invoke TECO without specifying a file-spec, TECO will read its
 memory logical and re-edit the last edited file.  TECO's memory
 feature is completely inhibited by the /NOMEMORY qualifier.
*Qualifiers
/FIND
 Initially position to (find) the last marked position in the input
 file.  Position is marked with the VTEDIT ESCape-F commands.
/INSPECT
 Simply read the file-spec, don't create a new edited copy.
/NOCREATE
 Do not automatically create a new file if the file specified by a
 TECO command doesn't already exist.
/NOINI
 Do not attempt to find or use TECO's private initialization
 logical TEC$INIT.
/NOMEMORY
 Do not read, create, or use TECO's memory logical TEC$MEMORY.
/SCROLL
 Automatically enter split screen scrolling mode.  The bottom 1/4 of
 the screen's lines are scrolled.  /SCROLL:n sets the number of lines
 to scroll to n.
/VTEDIT
 Automatically invoke the TECO keypad editor VTEDIT.
/VTEDIT:HOLD
 Set the VTEDIT keypad editor into hold screen mode.
/VTEDIT:SEEALL
 Set the VTEDIT keypad editor into SEEALL mode.
/VTEDIT:HOLD:SEEALL
 Set the VTEDIT keypad editor into both hold screen and SEEALL modes.
