FIle I/O

[Graham Nicholls]

Thanks.  I figured that it was a duplicate definition, but not if I leave out
st.stream, then OpenException is undefined.  Is there a documentation for the
exceptions which are in the relevant packages - I'll struggle without it!

And thanks, all for the help - much appreciated.

BTW, am I making a mistake using 2.0 rather than v1.x?
It seems that perhaps 2.0 is not entirely complete - the libraries are pretty
fundamental, after all.
Thanks again.
