How do you expose variable array components?

I'm stumped on how to expose the components of a variable array. For example:


1) If I create the following variable array:

$$test[1] = "abc"

$$test[2] = "def"

When I call the base variable $$test, FMP only shows the first value in the array. The data viewer only shows the same. What if I want to determine how many values are in my array? I can't seem to expose that information. Even ValueCount( $$test ) only returns a value of 1.


2) If I create the following variable array:

$$test["a"] = "123"

$$test["b"] = "456". When you call the base variable $$test, FMP displays nothing. Calling $$test["a"] will return the correct value that was stored. However, I see now way to expose the array as having two values, in repetitions "a" and "b".


Worst case, I could set the first repetition of the array as an index for the rest of it, but that seems kludgy. Can anyone shed additional light on a native FM method for exposing the contents of an existing array variable?
