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)

Example (JavaScript)

// LBound Example
/* LBound returns lower bound of array dimension */

LBound = function(arr, dm) {
  return 0; //JavaScript always begins with 0
}

var Other, Children=new Array(3), Parents=new Array(3,1);
Other = new Array("Damien" , "Pip" , "Wendy");
NSB.Print("'Other' Lower Bound: " + LBound(Other));
NSB.Print("'Children' Lower Bound: " + LBound(Children, 1));
NSB.Print("'Parents' Lower Bounds: " + LBound(Parents)+ " " + LBound(Parents, 2));

Output

'Other' Lower Bound: 0
'Children' Lower Bound:    0
'Parents' Lower Bounds:    0      0
