The EDT editor is the standard DEC supported editor for the VAX. It
provides good full-screen editing when used with VT-52 or VT-100
terminals. It may be invoked by user application programs, allows keys
to be software-programmed, has a macro definition capability which lets
you define your own commands, supports multiple text buffers, and even
has a good basic line-editing mode for non-DEC terminals.  A good way to
get started with EDT is to run the EDTCAI tutorial program, using a
VT-100 compatible terminal.  The EDT program itself has an extensive
HELP facility, available by typing HELP in line mode, or hitting PF2 in
screen mode.   Several editors are available through the EDIT command
(see HELP EDIT for details), but EDT is now the default. 
 
Other editors are available for users already familiar with them:

     SOS       -  The old line editor. May be dropped soon.
     TECO      -  Early  DEC  character editor.
     WYLVAX    -  SLAC's WYLBUR,  for advanced line editing.
