Thanks Matz.

Sorry, should have posted a bit more information to start with. I'm
running under SuSE Linux 8.2, kernel 2.4 (can't find the full version
number). ruby -v reports:

ruby 1.6.8 (2002-12-24) [i686-linux]

After having problems with a similar statement as the first statement in a
program, I tried creating a new program with just the one line I posted
above. That shorter program also returns the "wrong argument type nil
(expected String)" error. However, typing the same line into irb works
fine and returns 0 (and after doing so, typing Dir.getwd into irb returns
the expected "/").

Grateful for any help you can provide.
