You're about to have a very good time. :)

Explicit connection isn't needed - libURL handles that for you whenever
you use one of its file transfer commands.

put url ("file:"& tMyLocalFile) into url tMyServerUrl

Where tMyServerUrl is in the standard format for including protocol,
login, and password, e.g:

ftp://user:password@ftp.domain.com/folder/filename.txt

Same thing but in reverse:

put url tMyServerUrl into url ("file:"& tMyLocalFile)

Yep, thanks to Dave Cragg and the others who've worked on Rev's libURL,
it's that easy. :)

There's a lot more libURL can do too, including providing callbacks to
let you know when a file is done transferring so you can take further
action, or providing status updates during the transfer so you can use a
progress bar.  But for small text files you probably won't need a
progress bar because they'll transfer so fast.  Just check "the result"
after each libURL call to see if anything went wrong, and take
appropriate action from there:

put url tMyServerUrl into url ("file:"& tMyLocalFile)
if the result is not empty then
    answer "An error occurred while downloading: "& the result
    exit to top
end if

Complete docs and other helpful notes on libURL are in the RevTalk
Dictionary and here:
