Thanks very much for your help and for the explanation. The confusion I had
wasn't with how to define a tuple but with how to integrate the code to do
that with your code - I'm only just getting the hang of combining results
using bi/tri/cleave and I couldn't figure out how to apply anything like
that when dealing with the "scan" words that are used incrementally and are
stateful so they can only be called once. When I'm done with work I'm
probably going to reverse engineer the code you wrote which I see seems to
have added the tuples via using an association list?? I'm not quite sure.
I'm also getting a bit worried about the UI aspect.. I notice there are
some UI words which seem to be undocumented like <checkbox> but I wonder if
there is a way to display standard message windows or in particular a file
chooser. I know you mentioned that there is one under Cocoa but I haven't
found one under windows or a word that works on either platform (does
Factor have platform conditional compilation?)
