Function Reference
UBound
Returns the size of array dimensions.
UBound ( Array [, Dimension] )
Parameters
Array The array variable which is being queried.
Dimension

[optional] Which dimension of a multi-
dimensioned array to report the
size of. Default is 1, which is the first dimension. If this parameter is
0, the number of subscripts in the array is returned.

Return Value
Success:

Returns the size of the array dimension.
Failure:

Returns 0 and sets @error:

1 = Array given is not an array.
2 = Array dimension is invalid.
