Hi Chris,
Your method of loading the SBE-Quinto repository from the URL and
running it that way seems to work fine, so does this mean I introduced
the syntax error myself? Or does this mean that the fact that I am
using a different repository has something to do with why it works
this way?
I am still a little too green to figure out where I went wrong.
Everything was working up until this point.
Thanks
Dave

Hi, Squeak is really cool so far, but I have finally hit a snag I
can't seem to figure out, and I think it may have something to do
with the fact that I am attempting to run the SBE on a slightly
newer version of Squeak maybe?
I am on page 43 of the SBE book and I get the following syntax
error when I follow this instruction:
"In a workspace, type SBEGame new openInWorld and do it ."
Thanks!

When I go to http://www.squeaksource.com/SqueakByExample I see
that the example code for the book is available.
I click on Tools in Squeak and select MonticelloBrowser. I then
hit AddRepository, click HTTP, and then add SqueakByExample after
http://www.squeaksource.com in location:. I accept and close the
window. Click Open. In the new window click SBE-Quinto on the
left. Then press Load.
Now open a Workspace. Type:
SBEGame new openInWorld
highlight it and do it. Then you'll see the game.
This was in a 4.4 alpha build number #12186, which is very recent.
So, as far as I cans see, the Quinto game mentioned on pg. 43 of
SBE still works.
Chris

If you follow the book, the next paragraph on pg. 43 says:
The game will open, and you should be able to click on the cells and see
how it works.
Well, so much for theory. . . When you click on a cell, a notifier
window called the PreDebugWindow window appears with an error message!
As depicted in Figure 2.12, it says MessageNotUnderstood:
SBEGame»toggleState.
So I'm not sure it's supposed to work at that point. I think it's making
a point about the Debugger or something.
Incidentally I don't know why it says "and do it", as "new openInWorld"
seems to be enough.
You have another repository? OK.
At any rate this version seems to work alright. I always prefer to use a
working example and see how it works. I wouldn't sweat the details to
much. It sounds like you're getting the general idea of things.
HTH,
Chris
