Referring to hierarchical arrays

[Alan Beban]

After

myArray3 = Array(myArray1, myArray2)

How do I refer to it? How, for example, do I check to see whether myArray3 has arrays as elements?

And how do I access them if they exist? myArray3(1) didn't work for me.

Thanks.

Instead of theory let me offer you hands-on experience (key elements in blue ):
