Hi ---,

For such problems there is another nice tool called Method Finder. There you can insert all your objects, parameters and the result and Smalltalk try to find a proper method for your needs.
I have found the swap method with the following message: #(a b). 1. 2. #(b a).
>From my Array (#(a b)) i'm looking for a method with two parameters(index) to get the result of #(b a)

Kind regards,
Michael
