True. Here's some basic tests (-> means "returns"):
Is a Variable an Array?
------------------------------
Rev 2.x:
the keys of <variable>
--> If empty, <variable> is not an array
Rev 3.x:
<variable> is an array
--> "true" if it is, or "false" if it isn't
What are the elements of an array?
-----------------------------------------------
put the keys of <arrayVariable>
-> return-delimited list of elements
How many elements are in the array?
-------------------------------------------------
put the number of lines of (the keys of <arrayVariable>)
-> the number of elements
Does an element in an array have a value?
------------------------------------------------------
put <arrayVariable>[<key>] is not empty
-> "true" if it has a value, "false" if it does not
Has an element in an array been defined yet?
------------------------------------------------------------
put <key> is among the lines of (the keys of <arrayVariable>)
-> "true" if it has been defined, "false" if it has not been defined
