Sort of a general question:


Is there any way to get a count of the number of elements in an array?


So if I have:

$blah[1] = "hi"

$blah[2] = "there"


is there any way in FMP to find out that there are 2 elements in this array?


If not, what's the best way to loop through an array if you don't know how many elements are in it?


I tried

set var $greeting = $blah[3]

just to see what happens, but it didn't look like it generated an error I could test for.
