The [LBOUND](LBOUND) function returns the smallest valid index (lower bound) of an array dimension.

## Syntax

> result% = [LBOUND](LBOUND)(arrayName[, dimension%])

## Description

* arrayName specifies the name of the array.
* dimension% specifies the dimension number, starting with 1 for the first dimension.
  * If omitted, dimension% is assumed to be 1.
  * If dimension% is less than 1 or is greater than the number of dimensions, a [ERROR Codes](ERROR-Codes) error occurs.
* [LBOUND](LBOUND) and [UBOUND](UBOUND) are used to determine the range of valid indexes of an array.

## Example(s)

```vb

DIM myArray(5) AS INTEGER
DIM myOtherArray(1 to 2, 3 to 4) AS INTEGER

PRINT LBOUND(myArray)
PRINT LBOUND(myOtherArray, 2)

```
