Dear HUMANISTs,
As you see, use, hear about, or read about software or hardware
that you would like to see reviewed in the BITS & BYTES REVIEW,
please drop me a line on BITNET and let me know:
(1) The name of the program or hardware,
(2) What computer it runs on or is used with,
(3) And the phone number or address of the company that
manufactures the program.
The BITS & BYTES REVIEW reviews commercial and noncommercial
programs for Macintoshes and IBM compatibles.
Thank you.
Sincerely,

I am afraid this has grown into a longish technical
report. To understand current discussions on ISO standards, it is
necessary to know some of the history of these discussions.
We must begin with the basic structures of ISO character
sets. They have a minimum of 2 parts: a C-set (= control charac-
ters) and a G-set (= graphic characters). This is clearly laid
out in ISO 2022-1986. This standard first appeared in 1973 and
establishes code extension techniques for ISO 7-bit and 8-bit
coded character sets. One can have multiple C and G sets and in
the latest version even multiple byte G sets. In 7-bit ASCII we
have a C0 (= control characters in the first 32 positions) and a
G0 set (= SPACE (32), 94 graphic characters, and DEL (127)). This
G0 set has been further defined by ISO-646. The latest draft
proposal for revision of 646 I have seen is dated April 1989. In
fact it has two versions, one called the Basic code table (with
decimal positions 35-36, 91-94 and 123-126 reserved for country
specific characters) and the other 646-IRV (International
Reference Version).

[A complete version of this announcement is now available on
the file-server, s.v. ISO STANDRDS. A copy may be obtained
by issuing the command -- GET filename filetype HUMANIST -- either
interactively or as a batch-job, addressed to ListServ@UToronto and
*not* to Humanist. Thus on a VM/CMS system, you say interactively:
TELL LISTSERV AT UTORONTO GET filename filetype HUMANIST; to submit
a batch-job, send mail to ListServ@UToronto with the GET command as
the first and only line. For more details see your "Guide to Humanist".
Problems should be reported to David Sitman, A79@TAUNIVM, after you
have consulted the Guide and tried all appropriate alternatives.]
