- I. THE RESOURCE HANDBOOK
- In dealing with many people over the past two years as a result of my
- activity with the Ada Software Repository, I found many questions to be
- repeated time and again; I felt that something basic was missing from the
- available documentation. I also noticed that a lot of my answers were
- coming from a large number of notes and papers that I had collected over the
- past eight years; the stack of material was almost a foot high.
- Updating and putting these notes together into a useful book format
- seemed to be a good answer to the problem of bringing this information to
- the user community. The book would provide one place for the user to go in
- order to obtain the basic answers to his questions, and the book would also
- provide pointers to sources of more extensive information. This book, The
- Ada Software Repository and the Defense Data Network: A Resource Handbook,
- has been written and is scheduled to be available in mid-December. It is
- being published in paperback, and this newsletter will provide more details
- on its price and acquisition in future issues.
- The main topics covered by this book include:
-
- o A History and Tour of the Defense Data Network, the Ada
- Software Repository, and Several Major Software Repositories
- and Information Resources on the Defense Data Network (DDN)
-
- o How to Use the DDN and its Facilities - Electronic
- Mail, File Transfer Protocol (FTP), Remote Terminal (TELNET),
- and the Terminal Access Controller (TAC)
-
- o How to Access the Defense Data Network (and SIMTEL20)
- from BITNET, CSNET, USENET, and other computer networks
-
- o SIMTEL20 and Its Repositories of Software:
- - the Ada Software Repository
- - the three CP/M repositories
- - the two IBM PC repositories
- - the UNIX/C repository
- - the ZCPR3/Z System repository
- - the Miscellaneous repository
-
- o How to Find Out What is in the Ada Software Repository,
- How to Use the Ada Software Repository, and How to Keep in
- Touch with the Ada Effort Through the DDN
-
- o Electronic Mailing Lists on the DDN and What They Offer
-
- o How to Communicate and Transfer Files between Network-
- based Mainframe Computers and Personal Computers

- II. ASR-RELATED INFORMATION
- A. Archive Server. Archive Server is of interest to ADA-SW
- subscribers, particularly those who do not have direct access to SIMTEL20.
- It allows anyone to acquire files from the ASR via email (however, it is
- preferred that DDN users employ FTP). To get started using it, read the
- feature article in the latest newsletter or send an email message to:
-
- ARCHIVE-REQUEST@SIMTEL20.ARPA
-
- This email message should contain only one line:
-
- SEND HELP
-
- Archive Server will send a message back, introducing itself and leading
- you from there. The reader may also refer to ASR Newsletter 7 and the new
- book (discussed above) for more details on the Archive Server.
-
- B. Archive Server Cannot Be Accessed Through SEISMO.CSS.GOV. Several
- ASR users on the USENET have attempted to access the Archive Server through
- the host computer named SEISMO.CSS.GOV. Due to the large volume of
- electronic mail generated by the Archive Server, the administration at
- SEISMO has decided to disallow email traffic from the Archive Server. Any
- such request is returned to the USENET-based sender with the message:
-
- "554 simtel20.arpa!archive-request... UUCP Forwarding to / from archives is
- not permitted because of the cost . Sorry ."
-
- Alternate paths for USENET users exist, however, so the USENET is not
- locked out from using the Archive Server. These paths include:
-
- ...!ucbvax!simtel20.arpa!archive-request
- ...!uw-beaver!simtel20.arpa!archive-request
- ...!decwrl!simtel20.arpa!archive-request
- ...!lll-crg!simtel20.arpa!archive-request
-
- C. File Compression and the Archive Server. There have been a number
- of requests for information on where to find unsqueezing programs and the
- like, particularly from VAX/VMS users. Some useful items:
-
- 1) the directory PD:<CPM.VAXVMS> contains some tools for such functions
- specifically written to run on VMS
-
- 2) the directory PD:<UNIX.CPM> contains most of the needed tools
- written in C to run under various flavors of UNIX; they may be ported to VMS
- (on the VAX) and other environments with some effort
-
- ---------------------------------------------------------------------------
- III. INFORMATION OF GENERAL INTEREST
- A. PC SAM. The DDN Network Information Center (NIC) is pleased to
- announce a new IBM-PC software package for Simple Access to electronic Mail
- (SAM). SAM is a total communication and mail management system that makes
- electronic mail fast, efficient, and easy to handle on a PC. SAM can help
- you get the maximum benefit from DDN electronic mail, especially if your
- mailbox is on a heavily loaded host.
-
- At the push of a key, SAM will connect to your mail host, retrieve any
- messages in your mail file, and move them automatically to your PC. Using
- SAM, you can read and compose mail on your PC thus saving connect time and
- avoiding the delay of working on a slow host. Once messages are composed
- and ready to go, SAM will automatically send them to the mail host for
- online delivery.
-
- SAM currently works with 4 host mail programs: MM, UNIX Mail, VMS
- Mail, and InfoMail.
-
- Additional SAM features:
-
- . A built-in EDITOR for editing messages and DOS text files
- . Desk-like screen display with IN, OUT, and other FILE BASKETS
- to hold your documents
- . A personal online ADDRESS BOOK
- . A LEARN script facility
- . Programmable function keys
- . VT100 emulation
- . XMODEM and KERMIT file-transfer capability
-
- SAM was developed jointly by SRI International, Menlo Park, CA and the
- Transend Corp., Portola Valley, CA under sponsorship by the Defense
- Communications Agency. It has been beta-tested at four representative sites
- on the network.
-
- Trial disks will be available in November. For more information, FTP
- or request from SRI-NIC the file NETINFO:SAM-INFO.TXT. (Send messages to
- SAM@SRI-NIC.ARPA).
-
-
- B. DDN Maps. The June 86 issue of the ASR newsletter mentions the
- availablity of LOGICAL and GEOGRAPHIC MAPS of MILNET and ARPANET (pg. 6)
- that is free of charge. I neglected to mention that both the DDN DEFENSE
- DATA NETWORK BROCHURE and the LOGICAL and GEOGRAPHIC maps of the MILNET and
- ARPANET are available from the NIC.
-
- C. Beta Test Sites Needed for RADC's Ada Compilation System. Beta test
- sites are being sought for RADC's Ada Compilation System (ACS) developed by
- Intermetrics, Inc.
-
- The ACS runs on IBM 370, 43XX, and 30XX computers as well as plug-
- compatible machines such as those made by Amdahl. The UTS operating system
- (2.3) is a UNIX variant and is available from Amdahl either in "native mode"
- for Amdahl 580-series machines or on top of VM on IBM machines. Over 98% of
- the Ada Compilation System is written in Ada and consists of approximately
- 400,000 lines of source code.
-
- The compiler has been validated with ACVC 1.8 and executes at 250 to
- 400 lpm on the IBM 4341 with an Ada to assembly language expansion ration of
- 1 to 4. The compiler also contains a comprehensive global optimizer.
-
- It performs four major classes of optimizations:
-
- Ada-specific optimizations (such as constraint-check
- minimization and Haberman-Nassi Tasking),
-
- classical optimizations (such as common subexpression
- elimination and dead code elimination),
-
- register optimization, and
-
- branch optimization.
-
- Other compiler features include a partial implementation of Ada Chapter
- Thirteen, extensive syntax error recovery, compilation statistics gathering,
- and generation of source, object and symbol/cross-reference listings.
-
- Because of the emphasis on optimization, configuration management
- support, and capacity, the ACS is suitable for developing large, time-
- critical Ada applications. The ACS was developed in accordance with the
- Military Standards for Software Development, and is documented.
-
- One week User and Maintenance courses will be given in the January 1987
- time frame. RADC focal point is Donald L. Mark:
