2 EDT
  Invokes the EDT interactive text editor. This version of EDT
  contains the following enhancements:
 
  o file locking. No two people can edit the same file
  o use of wildcards in specifying file-spec.
  o filename memory. The editor remembers the last file you edited.
  o XLATE support

  Format:

    EDT file-spec
3 Parameters

 file-spec

  Specifies the file to be created or edited using the EDT editor.  If
  the file does not exist, it is created by EDT.

  The EDT editor does not provide a default file  type  when  creating
  files; if you do not include a file type, it is null.  The file must
  be a disk file on a Files-11 formatted volume.

  Full wildcard characters are allowed in the file specification.
3 Command_Qualifiers

/COMMAND

 /COMMAND[=file-spec]
 /NOCOMMAND

  Determines whether or not EDT uses  a  startup  command  file.   The
  /COMMAND  file qualifier should be followed by an equal sign and the
  specification of the  command  file.   The  default  file  type  for
  command files is EDT.

  The following command line invokes EDT to edit a file named MEMO.DAT
  and specifies that EDT use a startup command file named XEDTINI.EDT:

       $ EDT/COMMAND=XEDTINI.EDT MEMO.DAT

  If you do not include the /COMMAND=command file qualifier, EDT looks
  for  the  EDTSYS logical name assignment.  If EDTSYS is not defined,
  EDT    processes    the    system-wide    startup    command    file
  SYS$LIBRARY:EDTSYS.EDT.   If this file does not exist, EDT looks for
  the EDTINI logical name assignment.  If EDTINI is not  defined,  EDT
  looks  for  the file named EDTINI.EDT in your default directory.  If
  none of these files exists, EDT begins your editing session  in  the
  default state.

  To prevent  EDT  from  processing  either  the  system-wide  startup
  command  file  or the EDTINI.EDT file in your default directory, use
  the /NOCOMMAND qualifier as follows:

       $ EDT/NOCOMMAND MEMO.DAT

  No wildcard characters are allowed in the file specification for
  the command file.

/CREATE

 /CREATE
 /NOCREATE

  Controls whether EDT creates a new file  when  the  specified  input
  file  is  not  found.  Normally, EDT creates a new file to match the
  input file specification if it cannot find the requested  file  name
  in  the  specified  directory.   When  you  use /NOCREATE in the EDT
  command line and type a specification  for  a  file  that  does  not
  exist,  EDT  prints  an  error  message  and  returns you to the DCL
  command level as follows:

       $ EDT/NOCREATE NEWFILE.DAT
       Input file does not exist
       $

/JOURNAL

 /JOURNAL[=journal-file]
 /NOJOURNAL

  Determines whether EDT keeps a  journal  file  during  your  editing
  session.   The default file name for the journal file is the same as
  the input file name.  The default file type is  JOU.   The  /JOURNAL
  qualifier  enables you to use a different file specification for the
  journal file.

  The following command line invokes EDT to edit a file named MEMO.DAT
  and specifies the name SAVE.JOU for the journal file:

       $ EDT/JOURNAL=SAVE MEMO.DAT

  If you are editing a  file  from  another  directory  and  want  the
  journal  file  to  be  located  in  that directory, you must use the
  /JOURNAL qualifier with  a  file  specification  that  includes  the
  directory  name.   Otherwise,  EDT  creates  the journal file in the
  default directory.

  The directory that is to contain the  journal  file  should  not  be
  write protected.

  To prevent EDT from keeping a record of your  editing  session,  use
  the /NOJOURNAL qualifier in the EDT command line as follows:

       $ EDT/NOJOURNAL MEMO.DAT

  Once you have created a journal file, use the /RECOVER qualifier  to
  have EDT process the commands contained in the journal file.

  No wildcard characters are allowed in the file specification for
  the journal file.

/OUTPUT

 /OUTPUT=output-file
 /NOOUTPUT

  Determines whether EDT creates an output file at  the  end  of  your
  editing  session.  The default file specification for both the input
  file and the output file is the same.  Use the /OUTPUT qualifier  to
  give  the  output file a different file specification from the input
  file.

  The following command line invokes EDT to edit a file named MEMO.DAT
  and gives the resulting output file the name OUTMEM.DAT:

       $ EDT/OUTPUT=OUTMEM.DAT MEMO.DAT

  You can include directory information as part of  your  output  file
  specification to send output to another directory as follows:

       $ EDT/OUTPUT=[BARRETT.MAIL]MEMO.DAT MEMO.DAT

  The /NOOUTPUT qualifier suppresses the creation of an  output  file,
  but  not  the  creation  of a journal file.  If you are testing some
  edits and are not  sure  you  want  an  output  file,  you  can  use
  /NOOUTPUT as follows:

       $ EDT/NOOUTPUT MEMO.DAT

  A system interruption will not  prevent  you  from  recreating  your
  editing  session  because  a journal file is still being maintained.
  If you decide you want to save your editing session, you can do  so,
  even  though you specified /NOOUTPUT, by using the line mode command
  WRITE to put the text  in  an  external  file  before  you  end  the
  session.

  No wildcard characters are allowed in the file specification.

/READ_ONLY

 /READ_ONLY
 /NOREAD_ONLY

  Determines whether EDT keeps a journal file and  creates  an  output
  file.  With the default /NOREAD_ONLY, EDT maintains the journal file
  and creates an output file when it processes the line  mode  command
  EXIT.   Using  the  /READ_ONLY  qualifier  is  like  using  both the
  /NOJOURNAL and /NOOUTPUT qualifiers.

  The following  command  line  invokes  EDT  to  edit  a  file  named
  CALENDAR.DAT, but does not create a journal file or an output file:

       $ EDT/READ_ONLY CALENDAR.DAT

  Use /READ_ONLY when you are searching a file.  If you then  want  to
  modify  the  file,  use  the  line  mode  command WRITE to save your
  changes.  Remember, however, that you have no journal file.

/RECOVER

 /RECOVER
 /NORECOVER

  Determines whether or not EDT reads a journal file at the  start  of
  the editing session.  The default is /NORECOVER.

  When you use the  /RECOVER  qualifier,  EDT  reads  the  appropriate
  journal  file  and  processes  whatever  commands  it contains.  The
  appropriate syntax follows:

       $ EDT/RECOVER MEMO.DAT

  If the journal file type is not JOU or the file name is not the same
  as the input file name, you must include both the /JOURNAL qualifier
  and the /RECOVER qualifier as follows:

       $ EDT/RECOVER/JOURNAL=SAVE.XXX MEMO.DAT

  Because /NORECOVER is the default  for  EDT,  you  do  not  need  to
  specify it in a command line.
