     Hi!  This is SED, the full screen editor.	It is easier and  more
natural to use than line or character editors, and is generally faster
too.  To  use  it, just  type.  You can move the cursor (which is that
blinking mark in the upper left corner) to other parts of the  screen.
To change existing text, just type over it.

     There  are  also  commands  to the editor.  They move the viewing
window around, insert or delete lines or spaces,  move text  from  one
place to another, search, and other useful things.

     For a summary of the editor commands see the file HLP:SED.HLP.
     For a tutorial manual see the file                DOC:SED.MAN.
     For complete editor documentation see the file    DOC:SED.DOC.

You  can  also get on-line help. Type "3" on the keypad and then any
command to get a description of that command.

To exit from SED type CTRL-Z.
