arrayname

Name of the array variable; follows standard variable naming conventions.

dimension

Whole number indicating which dimension's lower bound is returned. Use 1 for the first dimension, 2 for the second, and so on. If dimension is omitted, 1 is assumed.

The LBound function is used with the UBound function to determine the size of an array. Use the UBound function to find the upper limit of an array dimension.

The lower bound for any dimension is always 0.
