How to create an array that selects from arrays?

Question

Hi there,

Got the following code:

| Array1 Array2 Array3 |
Array1 := #(1 2 3).
Array2 := #(4 5 6).

Array3 := (0 to: 2) collect: [ :i | !Selection of: #({i of: Array1}{i of: Array2})].

But of course it doesn't work.. So my question is: How can I create an array where each element is a selection of array elements? 

Thanks!

Answer 1

| Array1 Array2 Array3 |
Array1 := #(1 2 3).
Array2 := #(4 5 6).

Array3 := 0 to: 2 collect: [ :i | !Selection of: (Array with: (i of: Array1) with: (i of: Array2))].

Expressions in curly braces are evaluated before the rest of the Smalltalk code is evaluated.

Is it possible to select the entire coontents of Array1 Or Array2 to  with a !hotVariable to populate a parameter field?
