Scott, You've declared it... my $drvname; ...but not initialised it(given it a value). So at the moment it has the special value 'undef' (which is treated as 0 in a numeric context, or '' in a scalar one). Try and do much with an undef and you'll get a warning, basically reminding you to do something with it. You can selectively turn this warning off, like the other bloke suggested, but once you start playing with undefs things can get a bit odd -it's best to avoid them, by keeping the warnings on. I think setting it as an empty string will do the trick: my $drvname = '';
Note that an undef is *treated* like an empty string in scalar context -that doesn't mean to say that it *is* an empty string. This idea only clicked for me the other day when someone suggested I read the perlsyn manpage (the declarations bit especially).
