UBound Function
Returns a Long containing 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 | Required. Name of the array variable; follows standard variable naming conventions. |
| dimension | Optional; Variant (Long). 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.
UBound returns the following values for an array with these dimensions:
Dim A(1 To 100, 0 To 3, -3 To 4)
| Statement | Return Value |
|---|---|
UBound(A, 1) |
100 |
UBound(A, 2) |
3 |
UBound(A, 3) |
4 |
