The LBound Function

The LBound function returns the smallest subscript for the indicated dimension of an array.

Note: The LBound for any dimension is ALWAYS 0.

Tip: Use the LBound function with the UBound function to determine the size of an array.

Syntax

LBound(arrayname[,dimension])

Example 1

dim a(5)
a(0)="Saturday"
a(1)="Sunday"
a(2)="Monday"
a(3)="Tuesday"
a(4)="Wednesday"
document.write(LBound(a))

Output:

0
