Getting a Grip on VBScript Arrays with UBound
The ubound function in VBScript returns the highest available element in an array.

In the following example code, the message box would display the number 10:
Note: To see the examples work for yourself, copy the code into notepad and save it as a *.vbs file (i.e. sample.vbs).
The ubound function can be useful in a number of situations. For example, it can simplify the logic of looping through the elements of an array.
The full syntax of ubound is: ubound(arrayname[,dimension]) . The optional dimension parameter is used in multidimensional arrays to specify which dimension is being referenced. A "1" indicates the first dimension, a "2" indicates the second dimension, ad infinitum.
