Thanks Loathe the isDefined() null test is better then causing errors
unnecessarily with EOF. They should update that blog.
I like your new spin but <cfscript> does not have any advantages over CFML
tags
because it all turns into a class anyway.
You can also do it in one liner like this:
<cfset reader = createObject("java",
"java.io.BufferedReader").init(createObject("java",
"java.io.FileReader").init("C:\top50HeldbyInsiders.txt"))>
<cfset line = reader.readLine()>
<cfloop condition="#IsDefined("line")#">
<cfoutput> #len(line)# #HTMLEditFormat(line)#</cfoutput><br>
<cfset line = reader.readline()> <!--- keeps the loop going here --->
</cfloop>
<cfset reader.close()>
My example does not look like it will loop but it does!
It's magic!
