:'(

Does anyone here know Smalltalk? I did a tutorial for making my first application using Visual Age Smalltalk, and I get an error like this when trying to make the app. into an executable:

There are no implementors of #format:caseRule: included in the packaged image.

Since this is a tutorial, I figured the application would work, but apparently it doesn't... any help would be appreciated, thanks.

*intrigued*
Isn't Smalltalk a long-dead language? Why would someone be interested in using it? Interesting.

(Sorry for not being helpful...)

I *think* there's a language called small that is used to write CS plug ins, it could be a variant of that.

It's a VERY strongly OOP language. We discussed it for a few classes in OOP, and it was very interesting. I don't think it's dead, it's fairly new. The interpreter is called Squeak.

Sorry I can't help, though :/

I thought smalltalk was from the 70s... IIRC, it was one of the first OOP languages. I know it introduced a lot of OOP concepts. I don't think it's used for anything now, I'm not sure if it ever was.

I am almost certain that Small Talk was the first OO programming language.

It might have been the first language to be completely object-oriented, but I don't think it was the first language to support OOP.
