Lifting terms to string

[Niels Christensen]

Hi,

say I have a variable X, the values of which
I'd like to convert to a string, e.g. if
X=2 then I'd like to produce "2". Is there a
way to do that in Erlang?

What I really want is a version of io:fwrite that
produces strings instead of writing to IoDevices.

Thanks,
Niels
