        Access to Ada* Information on the Defense Data Network
        ------------------------------------------------------
     
        The Ada-Info directory on the Ada20 computer is available
to authorized DDN users only.  It is an official source of
information on the Ada language and Ada activities.  Sponsored by
the Ada Joint Program Office and maintained by the Ada
Information Clearinghouse, this computer directory is used to
announce current events, general activities and to indicate the
status of various Ada compiler efforts.  The directory is resident
on the University of Southern California Information Sciences
Institute, System F (USC-ISIF), whose alias is Ada20, and is
accessible via the Defense Data Network (DDN).

           The DDN is a collection of approximately eighty
different computer networks representing DoD facilities, research
centers and academia throughout the free world.  All of the
networks are packet-switching systems with interconnections at
various locations.  Access to the DDN is controlled by the
Department of Defense.  To obtain access to the DDN it is first
necessary to have a computer directory or access to a directory
on one of the several thousand host computers comprising the
system.  The AJPO maintains two hosts at the ISI facility in
California: the Ada20 and the Adavax.  Access to these systems is
controlled by the AJPO and is limited to those individuals
providing a significant level of support to the Ada effort.  Once
access is obtained to one of these systems or to any other DDN
host, the system administrator will provide directory and
password information to the user.  The following is the procedure
for making a connection to the Ada-Info directory from a DDN
host.


For Ada20 Users:

        1.  Log into your directory on Ada20.

        2.  Type "Type <Ada-Info>Files.Hlp" for a listing of all help
            files in the Ada-Info directory.

        3.  To View one of the files from this listing, type
            "Type <Ada-Info>Filename.Ext" where 'Filename' is the name
            of a file in the listing.

        4.  To Copy one of the files from this listing to a local directory,
            type "Copy <Ada-Info>Filename.Ext Fileb.Ext" where 'Filename' is
            the name of a file in the listing and Fileb.Ext is the new local
            file name.


For users of other DDN computers supporting the FTP program:

        1.   From a directory on the other machine, invoke FTP.

        2.   Establish a connection to the Ada20.

        3.   When the 'Connection Opened' message is displayed; login by
            typing "Log Anonymous Username" where 'Username' is the user
            login name on the other machine.

        4.   When the 'User Logged in' message appears, type
            "Get <Ada-Info>Files.Hlp Fileb.Ext" where Fileb.Ext is
            the local filename to write.

        5.  To read a desired file(?), step repeated substituting the
            new filename for 'Files'.
