The program name "ARC" has been in use by Digital Equipment
Corporation since the 60's on their TOPS-20 mainframe operating
system.  This is the operating system we use at SIMTEL20.  Here is a
capture of the ARC command at the "@" system prompt followed by a help
response.

@arc 
?Filename was not specified

@help arc

The ARCHIVE command asks that a permanent off-line copy of the specified
files be made on magnetic tape, and prevents the disk copy (if retained)
from being modified.

Format:
        @ARCHIVE (FILES) filespecs,
        @@subcommands

where:  filespecs is a single file specification or  a  series  of  file
                specifications separated by commas,
        subcommands means that if the command line is terminated with  a
                comma, the following optional subcommand may be typed:

                RETAIN  causes  the  disc  copies  of  the  files  being
                        archived to be retained in your directory rather
                        than being deleted and expunged.

Whenever a file is taken off-line as a result of  your  ARCHIVE  command
(without  the  RETAIN  subcommand),  the  operator  sends a MAIL message
notifying the owner of the directory from which the file was taken.  For
this  purpose,  the  owner of the directory is defined to be the user or
users whose user names appear in a file  named  DIRECTORY.OWNER  in  the
directory.  If this file does not exist, the message is sent to MAIL.TXT
in the directory.  If neither file exists, no message is sent.

You cannot change the contents of files specified in an ARCHIVE  command
once  the command is given, even if the files are not immediately copied
to tape.

The files you specify in an ARCHIVE command ordinarily become  invisible
to  most  TOPS-20  commands  as  soon  as  the ARCHIVE command is given.
However, if the RETAIN  subcommand  is  also  given,  the  files  remain
visible.

Related Commands:       CANCEL ARCHIVE
                        DELETE (with ARCHIVE subcommand)
                        DELETE (with CONTENTS-ONLY subcommand)
                        DIRECTORY (with ARCHIVE subcommand)
                        DIRECTORY (with INVISIBLE subcommand)
                        DISCARD
                        INFORMATION ARCHIVE-STATUS
                        RETRIEVE
                        SET FILE INVISIBLE
                        SET FILE VISIBLE

Manual.
