Having created a dynamic, multidimensional array like so:

Dim gInfo() As String
ReDim gInfo(0 To 1, 0 To 1)

I understand that you can only change the size of the last dimension.
Once having created an array, though, how do you find the size of this
second dimension?

The following line would not compile ("expected Array"):

iSize = UBound(gInfo(1))

I expected gInfo(x) to return the xth array in this "array of arrays".
Is this not so in VBA? How then do you get the size of the second
dimension? Thanks in advance.
