John,

You can also do this with a single repeat for each.

repeat for each char thisCharacter in wholeFileVariable
     doSomethingWith thisCharacter
end repeat

See the example stack called read anything in RevOnline to see how it  
is done.  If you can scan your file sequentially, you can do anything  
you want to it in short order.  It just depends on the specific  
details you want to accomplish.
