UBound(array[, dimension])
Description
UBound returns a long value specifying the largest available subscript in the specified dimension of a given array. The required parameter, array, is any array variable. The optional parameter, dimension, specifies which dimension's upper bound is returned, beginning with the default, 1. If the array is empty, -1 is returned. (For Android 2.1, use array.length instead.)
Example (Basic)
Rem UBound Example
'UBound returns upper bound of array dimension
Dim Other, Children(3), Parents(3, 1)
Other = Array("Damien", "Pip", "Wendy")
Print "'Other' Upper Bound:", Ubound(Other)
Print "'Children' Upper Bound:", _
UBound(Children, 1)
Print "'Parents' Upper Bounds:", _
UBound(Parents), UBound(Parents, 2)
Output
'Other' Upper Bound:2 'Children' Upper Bound: 3 'Parents' Upper Bounds: 3 1
