Return Values:

Example:

<!--- create the array --->
<cfset tmp=arraynew(1)>
<cfset tmp[1]="a">
<cfset tmp[3]="c">
<cfset tmp[4]="d">
<!--- let's see it in all it's un-glory --->
<cfdump var="#tmp#" label="original array">
<!--- compacting - grindgrindgrind --->
<cfset newTmp=arrayCompact(tmp)>
<!--- show me --->
<cfdump var="#Newtmp#" label="New Compacted array">
<!--- now, the pudding --->
<cfoutput>
Looping new Array<br />
<cfloop from="1" to="#arraylen(newTmp)#" index="i">
index #i# = #newTmp[i]#<br />
</cfloop>
</cfoutput>

delim Temporary list delimiter. Defaults to |. No
