re: CFC arguments, passing large strings
My recommendation would be to initialize the CFC with the string as an initial argument, then call the different iterative methods without sending the string over and over: just modify the variable within the CFC after the init. Ex: cfcomponent displayName=stringModder cfset variables.myString = / cffunction name=init access=public cfargument name=myLongString type=string required=true / cfset variables.myString = arguments.myLongString / /cffunction cffunction name=replaceSmartQuotes access=public cfset variables.myString = replaceList(variables.myString, chr(145) , chr(146), ',') / /cffunction cffunction name=replaceLineBreaks access=public cfset variables.myString = replace(variables.myString, chr(13) chr(10), br /, all) / /cffunction /cfcomponent Then in the calling template: cfset stringObj = createObject(component, StringModder).init(form.bigTextValue) / cfset newString = stringObj.replaceSmartQuotes() / cfset newString = stringObj.replaceLineBreaks() / etc ...

RE: CFC arguments, passing large strings
I should have mentioned the CFC is stored in the application scope, so I can't do that...

RE: CFC arguments, passing large strings
Oh, well, if it's a singleton, then you're going to end up taking up those whacking great chunks of server memory on every request cycle. I would strongly consider moving it out of application scope for that very reason, but I certainly don't know the entire app structure so that's just a shot in the dark.

RE: CFC arguments, passing large strings
But if I wrap it in structure, then it would be passed by reference. Wouldn't this alleviate the memory usage issue?

RE: CFC arguments, passing large strings
Yes, that would work. I suppose it breaks encapsulation, since the scope of the struct is 'known' to the CFC, but it should accomplish what you're after. If you do that, you technically wouldn't even need return values from the CFC, since changes to made to the method argument, would be made to the actual struct variable in the calling template.
