that's cool, but a little bit too intense for an article on asynchronous
pluggable protocols that also has uses some simple rebol scripting in it
:)
I guess I'm gonna go with:
err: error? try[returnstring: to-string do f1/text]
either err = true[
append f2/text "No string output returned"
show f2][append f2/text returnstring
show f2]
and say that's it. After all I'm already showing how to extend any url
aware windows app with rebol, so I can slip a bit on the application.
