There is no concept of "files" in Ur/Web, and your life will be easier
as an Ur/Web programmer if you stick within the endorsed model where all
persistent state is in either the SQL database or cookies.
I believe your idea of the appropriate first "hello world" program is
misguided in roughly the same way as a C programmer deciding that he
needs to print "hello world" to the console as his first Haskell
program, despite the fact that monadic IO makes that task more complex
than expected, and despite the fact that IO and other side effects are
not core concepts in Haskell.

Hi, when I visited the introductory web page the language looked like
Standard ML and so I got curious and wanted to experiment with the
language. I was thinking of doing some experiment where I read some
file, do some processing, and then output the results. I think for
this I would have to link up to C. This would also allow me to
benchmark against Haskell.
