<div class="moz-cite-prefix">MCL had multithreading long before the
OS had it: <br>
</div>
<div class="moz-cite-prefix">It was a cooperative Multithreading
build on stack-groups: the compiler inserted checks and
task-switches; there existed run-reasons and arrest-reasons; <br>
</div>
<div class="moz-cite-prefix">you could even adjust how gentle it
should be in Multifinder regarding other applications (something
like *eventloop-ticks-in-background* ? (Memory is Fading)</div>
<div class="moz-cite-prefix">A remarkable piece of Software!</div>
<div class="moz-cite-prefix">I started with 1.3 when it was
delivered by Apple (1988?)</div>
<div class="moz-cite-prefix">Last Version i bought was 4.2 (PPC i

<div class="moz-cite-prefix">I used fred (the editor) to implement a
Software for a historian who had to analyse about 100 Interviews,
each about 50 Pages. She had a hierarchical List of Topics
regarding different aspects of the live of these persons and could
assign these topics to pieces of these textdocuments and thanks to
freds notion of buffer-marks, you could even edit the documents
without destroing your marked "text-blocks" ; Finally an export of
a really big Index showing reasons for Arrest, work, living, of
the victims was created in rtf Format and used to Document the
History of "Die Frauen von Hoheneck": A group of Woman arrested
for being not Conform to DDR politics. The created material was
used to write two Books: one for a historic correct analysation of
the Topic (a German "Enquete-Kommission"), and a novel about
theese People ("Die Spur der roten Sphinx"). I learned a lot about
german and russian history during that work, because the historian
was a really smart Person, and i learned a lot about using MCL to
its limits.<br>

<div class="moz-cite-prefix">It was really fun to develop in MCL, i
never found a replacement :-/<br>

My memory is that the UI framework in Object Lisp and, later,
CLOS, was much easier and more convenient to work with than other
ways of building classic Mac user interfaces. One reason is that
you could build up a UI interactively in real time by evaluating
Lisp expressions at the Listener. After the transition to CLOS,
you could make a working window that responded appropriately to
mouse events by saying
<div class="">
<div class=""><br class="">
</div>
<div class=""> (make-instance 'window)<br class="">
<div><br class="">
</div>
<div>I don't remember the exact Object Lisp syntax, but it was
similarly simple.</div>
<div><br class="">
</div>
<div>The Mac got threads in System 7, in the form of the
Thread Manager. If I remember right, MCL/CCL didn't get
thread support until the OpenMCL fork, though you could have
used MCL's toolbox interface to talk to the Thread Manager
before that.</div>

<div>Before OSX the Mac system was a cooperative multitasking
system using what is nowadays called green threads.</div>

<div class="">Some of us remember that building a
“well behaved GUI” for the Mac was a pain to code.</div>
<div class="">Did ObjectLisp and successors make this
any easier with their OOness?</div>
<div class="">Could I implement widgets that responded
to mouse clicks “on their own,”</div>
<div class="">or was there always editing of the
dreaded “main event loop” for each new widget?</div>
<div class="">Some examples, if handy, would be good
fodder for conversation.</div>
<div class="">Lastly, when did MacOS get full-fledged
threads?</div>
<div class="">Or, since I’m taking to MCL devs, when
did CCL start supporting threads?<br class="">
