if the array has never been allocated then it is NOTHING. If it is allocated but empty then the upperbound is -1. To eliminate NOTHING, allocate with upperbound of -1.
Dim ary1Str() as string ' Nothing
Dim ary2Str(-1) as string ' array with No elements
I use (-1) unless I have a size in mind to avoid problems.

Having to do it. I find it simpler to Dim ary1str(-1). It will pass right through
For I = 0 to Ubound(ary1Str)
....
Next
if ary1Str Is Nothing then Ubound(ary1Str) throws an error. Forms/Controls Resizing/Tabbing Control
