Returns the largest available subscript for the indicated dimension of an array.
UBound(arrayname[, dimension])
The Ubound syntax has these parts:
| Part | Description |
|---|---|
| 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. |
The Ubound is used with the Lbound to determine the size of an array. Use the LBoundto find the lower limit of an array dimension.
The default 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) | 99 |
| UBound(A,2) | 2 |
| UBound(A,3) | 3 |
