UBound

Return the largest subscript for an array dimension.

Syntax 
      UBound(arrayname[, dimension])


Key
   arrayname    The name of the array variable

   dimension    The array dimension as a whole number
                1 for the first dimension, 2 for the second etc
                (default=1)

The UBound function is used with the LBound Function to determine the size of an array. Use LBound to find the lower limit of an array dimension.

Dim Arr(5,10,12)
result = UBound(Arr, 1)
WScript.Echo result
