The issue is with "2D" and "3D" nomenclature, which can be misleading 
when trying to understand working with arrays in Rev.

Rev currently uses associative arrays, which allow a string to be a 
label associated with a data element.

That label string can be numeric giving you ordered elements, and can 
can include commas to give you some of the convenience of 
multi-dimensional arrays.

Just remember it's always a string: myArray[1,2] is the same as 
myArray["1,2"].

Associative arrays are flexible, useful in a great many circumstances 
that indexed arrays might be harder to work with.

There is a request in Bugzilla for fully-dimensional indexed arrays, and 
that'll be nifty when it's there, but in the meantime hopefull 
associative arrays will continue doing what you need.
