VBScript's arrays have quite a few limitations. You may have noticed if you try this:
You get this error:
To work around this, you need to declare the array without a size (or with a constant size, e.g. 0), and then re-dimension it from the variable. Here are two examples; one using a simple array, the other a multi-dimensional array:
Note that if you want to increase the size of an array within a loop, and want to preserve the existing values assigned to the array, you need to use the Preserve keyword (otherwise, the array gets erased and re-created, thus destroying all your values):
