This function is for BASIC compatibility. It is not available in pure JavaScript projects.
LBound(array[, dimension])
Description
LBound returns a long value specifying the smallest available subscript in dimension of an array, array. The required parameter, array, is any array variable. The optional parameter, dimension, specifies which dimension's lower bound is returned, beginning with the default, 1. The lower bound of any dimension of an array is always 0.
Example (Basic)
Rem LBound Example
'LBound returns lower bound of array dimension
Dim Other, Children(3), Parents(3, 1)
Other = Array("Damien", "Pip", "Wendy")
Print "'Other' Lower Bound:", LBound(Other)
Print "'Children' Lower Bound:", LBound(Children, 1)
Print "'Parents' Lower Bounds:", LBound(Parents), LBound(Parents, 2)
Output
'Other' Lower Bound: 0 'Children' Lower Bound: 0 'Parents' Lower Bounds: 0 0
