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

Syntax
UBound(arrayname[, dimension])

The UBound function syntax has these parts:

Part Description
arrayname Name of the array variable; follows standard variable naming conventions.
dimension 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.

Remarks
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.

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


Dim A(100,3,4)
Statement Return Value
UBound(A, 1) 99
UBound(A, 2) 2
UBound(A, 3) 3
