UBound

Returns the largest available subscript for the indicated dimension of an array.

Structure

UBound(arrayname[, dimension])

Parameters

arrayname - Required. Name of the array variable; follows standard variable naming conventions.

dimension - Optional. Whole number indicating which dimension's upper bound is returned. Use 1 for the first dimension, 2 for the second, and so on. If dimension is omitted, 1 is assumed.

Description

The UBound function is used with the LBound function to determine the size of an array. Use the LBound function to find the lower limit of an array dimension.

Example

The lower bound for any dimension is always 0. As a result, UBound returns the following values for an array with these dimensions:

Dim A(100,3,4)

UBound(A, 1) ' Returns 100

UBound(A, 2)' Returns 3

UBound(A, 3)' Returns 4 |
