Words in Quackery take zero or more arguments from the (programmer accessible) data stack, and return zero or more results to the data stack.
In this dialogue in the Quackery shell, <code>/mod</code> takes two arguments and returns two results, <code>pack</code> takes three arguments (the topmost argument on the stack (<code>2</code>) specifies how many more arguments it is to take from the stack), <code>echo</code> takes one argument and returns no results, and <code>cr</code> takes no arguments and returns no results.
<pre>/O> 123 7 /mod
...
Stack: 17 4
/O> 2 pack
...
Stack: [ 17 4 ]
/O> echo cr
...
[ 17 4 ]
Stack empty.</pre>
Words can also take one or more items (nests, words or numbers) and arbitrary strings of text following the word as arguments. For example, <code>times</code> performs the item following it a specified number of times, and <code>say</code> echoes the string following it to the terminal.
<pre>/O> 4 times [ 3 times [ say "badger" sp ] cr ]
... 2 times [ say "mushroom" sp ] cr
...
badger badger badger
badger badger badger
badger badger badger
badger badger badger
mushroom mushroom
Stack empty.
