          OpenVMS Frequently Asked Questions (FAQ)


                   This is the OpenVMS Frequently Asked Questions (FAQ)
                   posting for the comp.os.vms and comp.sys.dec usenet
                   newsgroups.

                               Suggestions and Updates Welcome!

                      Please send your suggestions for changes,
                      additions, or corrections directly to FAQ Editor
                      (hoff{atsign}hp{period}com)

                                 No Support Questions, Please

                      Please do not send technical questions to the
                      FAQ Editor (hoff{atsign}hp{period}com) . The FAQ
                      Editor (hoff{atsign}hp{period}com) is not in a
                      position to answer general questions, nor to
                      provide general product support. Rather, please
                      post your questions to the appropriate newsgroup,
                      or please contact your preferred hardware and/or
                      software support organization(s) directly.

                      Your understanding in this matter is greatly
                      appreciated.

                   If you believe any particular discussion worthy
                   of inclusion in a future edition of the FAQ and
                   particularly once you have or know both the question
                   and the answer, please then send the entire discussion
                   along to the FAQ Editor (hoff{atsign}hp{period}com) for
                   potential inclusion.

                   Do note that the FAQ Editor (hoff{atsign}hp{period}com)
                   takes URL link continuity seriously, and strives to
                   maintain current links. This is, however, a large
                   task, and it is only becoming more difficult. URL
                   link continuity is also something that you can
                   assist with, of course. If you should find a dead
                   link or a stale URL pointer, please notify the FAQ
                   Editor (hoff{atsign}hp{period}com) . If you have
                   or can find the current, correct or updated URL,
                   of course, that greatly assists the FAQ Editor

                                                                       iii

          FAQ File Formats and Production Information

                   This FAQ is available in ASCII text, Postscript,
                   Bookreader, and HTML, and potentially in other file
                   formats. Certain formats, such as the Adobe Acrobat PDF
                   conversion from the Postscript format, are provided
                   downstream from the FAQ text formatting, and are
                   provided and maintained by others.

                   As the HTML-format FAQ is not a single monolithic (and
                   accordingly large) HTML file, it is the most difficult
                   format to search using the most common standard
                   (platform-local) tools. Accordingly, the FAQ Editor
                   (hoff{atsign}hp{period}com) recommends downloading,
                   using and searching the ASCII text FAQ format.

                   The OpenVMS FAQ is maintained in DECdocument SDML
                   format and all FAQ maintenance and the primary output
                   file format conversions are performed on OpenVMS
                   systems. For information on the DECdocument product,
                   please contact Touch Technologies.

                   Introduction

          1.2  What are the OpenVMS Usenet Newsgroups?

                   There are a huge number of newsgroups available, some
                   of which discuss topics of interest to folks using
                   OpenVMS operating system. Key among these are the
                   comp.os.vms newsgroup and the vmsnet.* heirarchy of
                   newsgroups.

          _____________________________
          1.2.1  What is the scope of the comp.os.vms newsgroup?

                   The comp.os.vms newsgroup is the primary newsgroup
                   for discussion of the HP OpenVMS operating system and
                   the computer systems on which it runs. Questions about
                   layered products which run on OpenVMS are also welcome,
                   though many of them (in particular, language compilers
                   and database systems) have more specific newsgroups. If
                   a question has some relationship to OpenVMS, it belongs
                   in comp.os.vms/.

          _____________________________
          1.2.1.1  Using the Natural Language Search Assistant (AskQ)?

                   Keith Cayemberg has performed some some experimentation
                   on the HP Natural Language Search Assistant, and
                   reports the following formula for easing the effort
                   of locating OpenVMS Support content within NLSA.

          http://hp.ciber.net/hp/match.asp?query=Example+VMS&source=1000

                   You can replace the "Example+VMS" with the keywords you
                   wish to search for. Important for selecting the OpenVMS
                   content content is the "&source=1000" at the end.

                   Here is an extract from Keith Cayemberg's Programming

          1.2.2  What newsgroups carry VMS-related information?

                   The vmsnet.* hierarchy is operated by the Encompass
                   users group (formerly known as DECUS), and contains
                   various newsgroups of interest, including vmsnet.misc
                   and vmsnet.alpha.

                   Sprechen Sie Deutsch? Besuchen Sie bitte den newsgroup
                   de.comp.os.vms.

                   The comp.sys.dec newsgroup carries general discussions
                   about various HP computer systems, and specifically
                   systems that were acquired by HP as part of the
                   acquisition of Compaq, systems which had previously
                   been acquired by Compaq as part of the acquisition of
                   Digital Equipment Corporation (DIGITAL).

                   Also of interest are resources and conferencing systems
                   including Encompasserve (formerly known as DECUServe)
                   and Ken Farmer's OpenVMS.Org forums:

          1.2.3  What newsgroup archives are available?

                   Extensive archives of INFO-VAX mailings and
                   comp.os.vms postings are archived and available at
                   SRI International: ftp://crvax.sri.com/info-vax/

                   Google also has extensive newsgroup archives available

          _____________________________
          1.2.4  What is the INFO-VAX mailing list?

                   INFO-VAX is a mailing list which is bidirectionally
                   gatewayed to the comp.os.vms newsgroup. This means that
                   postings to comp.os.vms get automatically sent to INFO-
                   VAX subscribers and messages sent to the INFO-VAX list
                   are automatically posted to comp.os.vms

                   INFO-VAX can be a useful way to participate in the
                   newsgroup if you can't access the newsgroup directly
                   through a newsreader. Note that INFO-VAX is a closed
                   mailing list, which means that only subscribers may
                   post to it. Please see Section 1.2.4.1 for information
                   on how to subscribe, and how you can subscribe such
                   that you can post from multiple addresses but still
                   receive no more than one copy of the mailings.

                   Please remember that propogation delays can and do
                   vary, meaning that mailings and postings may be delayed
                   or even lost. It is quite possible that postings
                   may not be delivered for several days, and that some
                   postings will appear out of the expected order.

                   For details on the available archives, please see
                   Section 1.2.3.

          _____________________________
          1.2.4.1  How do I subscribe to or unsubscribe from INFO-VAX?

                   The address for subscription requests is Info-VAX-
                   Request[at]Mvb.Saic.Com. Subscription requests are
                   handled automatically by a mail server. This mail
                   server ignores the subject line and processes each
                   line of the message as a command.

                                                                       1-5
