22. LBound()
FUNCTION: Returns the base index value for a dimension of any array.
SYNTAX: Lbound(arrayname [, dimension])
ARGUMENTS: arrayname is the name of any array; dimension is an optional number indicating the dimension
to find the lower bound.
EXAMPLE: <%
i = Array("Monday","Tuesday","Wednesday")
response.write LBound(i)
