I'm working through the Squeak by Example book and ran into a snag. The code on
page 33 for the Quinto game is returning an error message. I have the SBECell selected and "-- all --" is highlighted in the right pane, just like in the book, but it responds with the message "Unknown variable: initialize please correct or cancel: / declare temp / declare instance / cancel". So I guess it doesn't recognize "initialize" and thinks I'm trying to create a variable? According to the book it should be recognized. Here's the code: initialize super initialize. self label: ''. self borderWidth: 2. bounds := 0@0 corner: 16@16. offColor := Color paleYellow. onColor := Color paleBlue darker. self useSquareCorners. self turnOff I even downloaded the code for the book from Squeaksource and pasted it in and it does the same thing. Any help would be appreciated. Thanks, - Eric (Dr. Zephy) _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

Sounds like a typo in your code. Maybe there is something wrong with your cut and paste (unicode and tabs drove me crazy in other languages - not in squeak so far). Select all in your initialize method with command-a, backspace, rewrite it from scratch. The tutorial should be okay, i did it twice with some newbies. bye Enno _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

I got an error here too, when I first did the example. I think I removed: self turnOff and the code worked. I was using the Cobalt image though. not sur if this helps. wfpi On 4/28/08, Dr. Zephy <[hidden email]> wrote: I'm working through the Squeak by Example book and ran into a snag.
