Sample code invoking the randomize function

The following example calls the Randomize function to seed the random number generator and generates 10 random numbers. 

<cfset randomize(12345)> <!--- if one was to remove this line, the random numbers are different every time ---> 
 <cfloop index="i" from="1" to="10"> 
 <cfoutput>#rand()#</cfoutput> 
 </cfloop>
