Thanks Rick. So, in the case for my file with 8500 lines... If I get the last 100 chars and then do a <find> on them, I should be good to go?

The following code shows that the listLast() method is *FAR* slower than the rightmost chars method. I read a file of 1800 lines, about 73kb... and performed both methods 10,000 times each.. the listLast method completed in around 5.5 seconds. The rightmost chars method completed in 80 MILLIseconds. <cffile action="READ" file="#ExpandPath(".")#\test.txt" variable="tempvar"> <cfoutput><p>File size: #len(tempvar)# characters.</p></cfoutput> <cfset startTime = now().getTime()> <cfloop from="1" to="10000" step="1" index="i"> <cfset foo = listLast(tempvar,chr(10))> </cfloop> <cfset endTime = now().getTime()> <cfoutput><p>ListLast method completed in #endTime-startTime# ms.</p></cfoutput> <cfset startTime = now().getTime()> <cfloop from="1" to="10000" step="1" index="i"> <cfset foo = right(tempvar,100)> </cfloop> <cfset endTime = now().getTime()> <cfoutput><p>Rightmost chars method completed in #endTime-startTime# ms</p></cfoutput> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Create Web Applications With ColdFusion MX7 & Flex 2.
