Example

<h3>ArrayNew Example</h3>
<!--- Create an array. --->
<cfset MyNewArray = ArrayNew(1)>
<!--- ArrayToList does not function properly if the Array is not initialized with
    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>
    <p>It has #ArrayLen(MyNewArray)# elements.</p>
    <p>Contents: #ArrayToList(MyNewArray)#</p>
<!--- The array has expanded dynamically to six elements with the use of ArraySet,
    even though we only set three values. --->
</cfoutput>
