I guess I don't understand why you need to create the array variable with the
Run Command syntax. Why not just create an empty array as you normally would in
your MapBasic program and then use ReDim to size the array to the necessary
number of fields:
Dim MyArray() As String
...some code...
ReDim MyArray(mysize)
