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 |

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!
