I see that someone has already answered the exception mechanism part of your question.

Here's the technique I use to set a larger memory space: D:\develop\squeak\v2_4b\Squeak.exe -memory: 64 "d:\develop\squeak\v2_4b<YOUR IMAGE NAME HERE>.image"

Excuse me, I am new to Squeak, but I have used a lot VisualWorks 3.0 & 2.5 There is an exception handling mechanism in Squeak? If so, where is it? (I search for signal class, Exception class....but I don't found them) If there isn't, I can build a small try-catch clone for Squeak....as a goodie... Do you think it will be a good idea?

Last but not least, I' d like to enlarge the memory space of Squeak (at the moment I am running out of memory :( ) How can I do it? I must use a special switch on invoking Squeak? I am using Squeak under Windows. thank you very much! -- // Giovanni Giorgi e-mail: giovanni.giorgi@mlab.disco.unimi.it // Master Thesis at http://mars.sal.disco.unimi.it/~giorgi // Student & (ex)Tutor at Depart. of Computer Science of Milan, Italy.
