-
- As NAVIGATING THE INTERNET: AN INTERACTIVE WORKSHOP gets closer to
- being over, you may want to continue getting information on the
- Internet by joining one of the many conferences that are available.
-
- The Public-Access Computer Systems Forum (PACS-L) is a popular
- computer conference that discusses current events that are taking
- place over the Internet. PACS-L
- is moderated so much of the duplication and repetition of an
- unmoderated conference is eliminated.
-
- To sign-up to PACS-L send the following e-mail message to
- LISTSERV@UHUPVM1.bitnet:
-
- SUBSCRIBE PACS-L FirstName LastName.
-
- After joining the conference you will receive a welcome that goes
- into detail of how to send messages and unsubscribe to the
- conference.
-
- Save that welcome message as a guide to joining lists on the net.
-
- In fact, PACS-L itself has become a searchable database and is a
- source of information on the Internet. Many topics that you may
- want to know more about--CD-ROMs, WAIS, Gophers, FREENETS,
- Electronic Copyright, NREN--and others have been discussed over the
- Internet on PACS-L or other computer conferences and many are
- searchable over the Internet.
-
- Other lists on the net act as databases and are sources of informtation
- and are searchable.
-
-
- Charles W. Bailey provides the
- following short description on searching a database like PACS-L.

- --------------------
- How to Search the PACS-L Message Database
-
- By Charles W. Bailey, Jr.
-
-
- Here's a brief tutorial on how to search the PACS-L message
- database and retrieve information. To get a more complete
- explanation, send a message to LISTSERV@UHUPVM1 that says:
-
- INFO DATABASE
-
- First, we are going to construct a batch job to search for
- all messages that have the term "Hypertext" in them, and we are
- going to ask for an "index" that will tell us which messages have
- this search term. To do so, we create an e-mail message with the
- following information in it, and we send it to LISTSERV@UHUPVM1
- (don't send it to PACS-L@UHUPVM1):
-
- //
- Database Search DD=Rules
- //Rules DD *
- Search Hypertext in PACS-L
- Index
- /*
-
- We get back two things. An e-mail message that tells us how the
- job went and the actual output file, called DATABASE OUTPUT.
- Here's the file:
-
- > Search Hypertext in PACS-L
- --> Database PACS-L, 137 hits.
-
- > Index
- Item # Date Time Recs Subject
- ------ ---- ---- ---- -------
- 000022 89/06/30 08:31 306 Common Knowledge Info.
- 000047 89/07/07 08:15 18 Hypertext Conference
- 000075 89/07/12 17:13 21 Hypertext & Hypermedia Articles
- 000088 89/07/13 16:19 17 CD-ROM Expo '89
- 000194 89/07/22 14:11 25 Hyperdoc
- 000248 89/07/30 20:00 23 Hypertext Hands-On!
- 000251 89/07/31 12:52 14 Re: Hypertext Hands-On!
- 000253 89/07/31 15:04 47 Was: Hypertext Hands-On!
- 000267 89/08/03 09:38 24 A New Journal -- Hypermedia
- 000311 89/08/11 12:18 23 Hypermedia & Optical Tech. Resources
- 000338 89/08/17 11:37 33 Hypermedia/Multimedia
- [The rest of the list is omitted.]
-
- We decide we want to see number 267 (the messages are numbered at
- the left). So we send a second job to LISTSERV@UHUPVM1 with the
- following lines in it:
-
- //
- Database Search DD=Rules
- //Rules DD *
- Search Hypertext in PACS-L
- Print all of 267
- /*
-
- We get back both an e-mail job status message and a file. The file
- contains the entire retrieved PACS-L message. Here's the message
- text.
-
- > Search Hypertext in PACS-L
- --> Database PACS-L, 137 hits.
-
- > Print all of 267
- >>> Item number 267, dated 89/08/03 09:38:14 -- ALL
- [The retrieved message is here.]
-
- To print multiple messages, just add the additional numbers:
-
- Print all of 267 311
-
- You can use these examples as JCL templates for your own searches.
- I have two template files (one per job stage) that I edit and
- "include" in the appropriate e-mail message for the server.
-
- Here's a brief summary of some more advanced search features.
-
- The Boolean "AND" operator is implicit:
-
- Search hypertext hypermedia in PACS-L
-
- You can also make the "AND" operator explicit:
-
- Search hypertext AND hypermedia in PACS-L
-
- The Boolean "OR" operator is explicit:
-
- Search hypertext OR hypermedia in PACS-L
-
- The Boolean "NOT" operator is also explicit:
-
- Search hypertext NOT hypermedia in PACS-L
-
- Terms can be nested:
-
- Search (hypertext OR hypermedia) AND multimedia in PACS-L
-
- You can also limit searches in the PACS-L message database by date.
-
- The first technique is to search for records in a date range.
- As you recall, the search request is sent to LISTSERV@UHUPVM1 as
- an e-mail message. Note how the dates are constructed.
-
- //
- Database Search DD=Rules
- //Rules DD *
- Search Hypertext in PACS-L from 91/1/1 to 91/4/30
- Index
- /*
-
- Another technique is to request messages since a specified date.
- Here is a sample search:
-
- //
- Database Search DD=Rules
- //Rules DD *
- Search Hypertext in PACS-L since 1/91
- Index
- /*
-
- A final technique uses the asterisk wildcard character to
- retrieve all messages in a date range:
-
- //
- Database Search DD=Rules
- //Rules DD *
- Search * in PACS-L from 91/4/1 to 91/4/30
- Index
- /*
-
- This search results in a handy index of all the PACS-L messages
- sent out in April 1991.
