Yes you are right. I thought the same. And im planning to implement a better way. For example that each cell gets its own life tracker. Then I could ask each cell idividually if it was alive at any point I want.
Furthermore i found out that there are such things as Gemstone or fuel wich one could use to extract data. So i will learn about those things aswell in the next time. Thanks for your answer and the hint :) -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
