Bah, so much for the 'Perl Pocket Reference' (where I 'checked' the parameters). ;)
Actually, although I don't use it much now, the 'Perl Pocket Reference' is a really handy little book. It has exactly the right amount of information in it for a quick reference and is well indexed. Highly recommended for Perl newbies (ikegami is not a Perl newbie btw)!
