I'm posting this message for a friend, who finds himself (temporarily)
without USENET access. Please reply by mail to him, and not to me- his

A while back I was asking questions about Object-Oriented languages of any
description. (I was csrdi@its63b at the time.) Since then I've heard of the
existence of a variety for the Mac, including Object Logo, Object Pascal and
Objective C. Since part of my final-year project includes a comparitive
languages survey, I'd like to get my hands on a few of these. So far, our Apple
supplier has only been able to track down Object Logo. According to an article
in BYTE (August 86), there are also an Object Pascal system (from Apple) and an
Objective-C sytem from PPI. Anyone know anything more about these systems,
particularly availability and cost? Please MAIL any info you've got to
rdi%ed.ecsvax@ukc.uucp
(rdi%ed.ecsvax@UKACRL from BITNET sites)
I am unfortunately off the net at the moment, although csrdi@its63b should be
back sometime.
For those who were interested in my project work, here's an update:
The first section will probably consist of a literature and language survey,
looking at what defines object-orientation and how well some of the existing
languages meet the definition.
This will probably be followed by a more theoretically-inclined section,
examing the semantics of Object-Oriented Languages and possibly also analysing
them as communicating systems, probably using either Hoare's CSP or Milner's
Calculus of Communicating Systems.
The initial idea, of specifying and implementing an OO language has been
dropped, since there's little point in adding yet another toy language to the
scene. What is more likely is the analysis will be done using Budd's Little
Smalltalk as an example system.
Thanks in retrospect to those who have replied to previous postings; apologies
to anyone who has tried to mail me and had it bounced.
For any responses to this, thanks in advance,
--Rick.
