EDT, the DEC Editor, has its own HELP files which you can access from 
 within EDT using the EDT HELP command.  To access EDT from MCR, use a
 command in the following form:

 EDT [outfile,][journal][=] infile[,command]

 The optional output filespec permits you to give a new name to the outfile.
 The journal filespec permits you to give a new name to the journal file.  The
 equals ( = ) is required if you use one of these two filespecs.  The infile
 is the file you wish to edit.  The optional command filespec refers to a file
 of EDT commands you wish to have read in and executed before you start 
 editing.

 You can use two qualifiers to the EDT command.

 EDT/RO infile means you wish read-only access to the file.  You cannot 
 edit it.

 EDT/RECOVER infile means you wish to use the EDT journalling facility to
 recover previous edits. 

 See the EDT Editor manual for more information on EDT.
