<h3>ArrayNew Example</h3>

ArraySet --->
<cfset temp = ArraySet(MyNewArray, 1,6, "")>

<!--- set some elements --->
<cfset MyNewArray[1] = "Sample Value">
<cfset MyNewArray[3] = "43">
<cfset MyNewArray[6] = "Another Value">

<!--- is it an array? --->
<cfoutput>
  <p>Is this an array? #IsArray(MyNewArray)#
  <p>It has #ArrayLen(MyNewArray)# elements.
  <p>Contents: #ArrayToList(MyNewArray)#

even though we only set three values --->
