[comp.lang.smalltalk] Garbage Collection

sukumar@ut-emx.UUCP (sukumar rathnam) (07/18/90)

The Smalltalk V 286 manual claims that:
Smalltalk purgeUnusedSymbols should remove unused symbols.
In my version i get a walkbalk about a message not understood.
Any clues on how this pblm can be solved would be appreciated.

Please reply by MAIL to sukumar@emx.utexas.edu

The repetitive sending of the Position Papers on Garbage Collection has
to be one of the best samples of techological irony I've seen in quite 
a while. Yikes!

In regards to the International Smalltalk Association (ISA) I recieved 
a number of messages and I would like to thank everyone for their 
ideas.  In response to some of the questions, here are some answers: 
 
Anyone can write for the newsletter, as a matter of fact, articles are 
desparately needed to get the show on the road and keep it there.
Currently I am the correct person to send articles to (yes, they can be
sent via NETMAIL).  They can be of any length (I reserve the right to 
edit them), you keep all rights to your work, by submitting the 
article you grant ISA permission to publish the article, and no, we 
don't pay.  However the fine print clearly states in invisible ink
that those of the sex you prefer will find you incredibly attractive
and you will get three of four offers a day for a one month period
after your article is printed.  We also offer a money back guarantee.
   
The names that I have added to the mailing list, by request, are: Ralph
Johnson, Richard Peskin, Kevin Twidle, and Eric Weitzman.  Robert 
Gayvert - I would really like to add you as well...but I'll need your 
address!
 
I agree that it would be a good thing to put the Public Domain 
Smalltalk code up on the net....but I'm afraid there is a little to 
much of it to be practical.  If there is a "better way", please let me 
know, I'll certainly do what I can.  The first volume I believe is 
around 300 kb, although I haven't looked it for quite a while now.  If 
you have any Smalltalk code you would like to put into the public 
domain please send a copy to me (preferably DOS format) at:
     
      Simulation Sciences inc.
      ATTN: Paul Regenhardt
      6000 East Evans Ave.
      Bldg 3, Suite 201
      Denver, CO 80222
    
I am currently compiling the 2nd volume and would like to see some more
stuff!  Currently the hottest thing in the second volume is the 
hypertext editor and hypertext display system.  Anyone who donates code
will automatically receive the second volume when it's compiled.  The
rest of you may have to suffer interminably (how's that for blackmail?)
