Question regarding arrays...

[Lynch, Jonathan]

Interesting - thanks!

Associative arrays should be perfect for what I need.

What would be the advantage to indexed arrays over associative arrays -
are they more quickly accessed?

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.
