UBound Function 

  • 發行項

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


UBound(arrayname[, dimension])

Arguments

  • 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.

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 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)
Statement Return Value

UBound(A, 1)

100

UBound(A, 2)

3

UBound(A, 3)

4
