UBound

This function is for BASIC compatibility. It is not available in pure JavaScript projects.

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)

'UBound returns upper bound of array dimension

       UBound(Children, 1)
Print "'Parents' Upper Bounds:", _
       UBound(Parents), UBound(Parents, 2)

'Children' Upper Bound:    3
