Hi Try this one: #(1 2 3) with: 'abc' do: [ :aNumber :aLetter | do something first with 1 and $a, then with 2 and $b, and finally with 3 and $c ] 2017-11-14 10:10 GMT+01:00 Prof. Andrew P. Black <black@cs.pdx.edu>:

What method will execute a two-parameter block with corresponding pairs of elements from two separate Ordered Collections.

something like this example:

#(1 2 3) and: 'abc' do: [ :aNumber :aLetter | do something first with 1 and $a,

then with 2 and $b,

and finally with 3 and $c ]

I searched for ‘corresponding’ and ‘pairs’ and failed to find what I’m looking for. I tried ‘zip’. It’s hard to search for this with an example.
