OK, I solved it - I think. I changed the code to:

You can substitute "nil" for "&result". I misunderstood what you were
trying to do with your example, so I told you how to read the separators
into the array, rather than the "data". The solution is to simply to do the
opposite of what I said -- "scanUpTo" into your result string and scan the
characters in your set into nil.
As for tutorials, I should have sent you this way the first time around:
http://developer.apple.com/techpubs/macosx/Cocoa/TasksAndConcepts/Programmin
gTopics/Strings/index.html
It covers strings, character sets and scanners.
