[Newbies] smalltalk and squeak

[James O'Brien]

Thank you for your suggestions.


I guess I'm thinking in terms of HyperCard. With HyperCard I could 
script a button, field, card, stack, etc. With Squeak, I can't figure 
out to change what the calculator's buttons do. If had created the 
calculator with HyperCard, I could easily change how its buttons work. 
Just open them and there's the script.

I've tried using the Browser, but can't access the Smalltalk code for 
the calculator, whether I create it with Smalltalk in the Workspace or 
build it using Morphic. Still don't get it.
