Using the '''array'''' library to multiply each value in an array by 10 and display the results:
<lang Retro>[ 1 2 3 4 5 ] ^array'fromQuote [ 10 * ] ^array'map ^array'display</lang>
Retro also provides '''^array'apply''' for use when you don't want to alter the contents of the array:
<lang Retro>[ "Hello" "World" "Foo" ] ^array'fromQuote [ "%s " puts ] ^array'apply</lang>
