View source for UBound

UBound(''array''[, ''dimension''])

== Description ==

UBound returns a long value specifying the largest available subscript in the specified dimension of a given array. The required parameter, ''array'', is any array variable. The optional parameter, ''dimension'', specifies which dimension's upper bound is returned, beginning with the default, 1.  If the array is empty, -1 is returned. (For Android 2.1, use array.length instead.)

== Example (Basic) ==

<pre>
Rem UBound Example
'UBound returns upper bound of array dimension

Dim Other, Children(3), Parents(3, 1)
Other = Array("Damien", "Pip", "Wendy")
Print "'Other' Upper Bound:", Ubound(Other)
Print "'Children' Upper Bound:", _
       UBound(Children, 1)
Print "'Parents' Upper Bounds:", _
       UBound(Parents), UBound(Parents, 2)
</pre>

== Example (JavaScript) ==
<pre>
// UBound Example
/* Length returns upper bound of array dimension + 1 */

var Other, Children=new Array(3), Parents=new Array(3,1);
Other= new Array("Damien" , "Pip" , "Wendy");
Parents[3]=''; //need to assign variable to use length on multidim array
document.write("'Other' Upper Bounds: " + ((Other.length)-1).toString() + "<br>");
document.write("'Children' Upper Bounds: " + ((Children.length)-1).toString() + "<br>");
document.write("'Parents' Upper Bounds: " + ((Parents.length)-1).toString() + "<br>");
</pre>
== Output ==

<pre>
'Other' Upper Bound:2
'Children' Upper Bound:    3
'Parents' Upper Bounds:    3      1
</pre>
