James is of course right. do: iterates over the values, if you want the whole associations, you use associationsDo: At least I was right about keysAndValuesDo: ;-) Joachim
myDict do: [:aValue | ]. âAn alias for #valuesDo:â

You can use do: with each Association as a parameter or you can use keysAndValuesDo:
myDic do: [:assoc| | key value| key := assoc key. value := assoc value. ...]. myDic keysAndValuesDo: [:key :value| ...]

I need to iterate over a dictionary.
I asked the AI buddy for a little help, and he says:
| myDictionary |
"Create a dictionary" myDictionary := Dictionary new. myDictionary at: 'one' put: 1. myDictionary at: 'two' put: 2. myDictionary at: 'three' put: 3.
"Iterate over the dictionary" myDictionary do: [ :key :value | Â Â Transcript show: key , ' -> ', value printString ; nl. ].
but when i try this, I get:
ArgumentsCountMismatch: This block accepts 2 arguments, but was called with 1 argument.
Is the AI using a different dialect of smalltalk?
how would I go about acting on each pair?
Thanks!
