different ways you could approach this. the easiest would probably be using arrays. for example:

var myBox = new Array(4);

Now you have a myBox with 4 slots for information. Now you can put information into the array by accessing each slot like this: myBox[0], myBox[1], myBox[2] and myBox[3] (arrays are always indexed from 0!!).
To output the entire array out an outlet you simply do: outlet(0, myBox), for individual elements outlet(0, myBox[2]).
Hope this is helpful.
