Use vars qw

[DavidHappyFeet]

Hi Everyone,

I'm totally new to Perl. Could anyone tell me what:

use vars qw(@ISA $VERSION $MAINTENANCE);

means?

Thanks in advance,

-David

it declares the list of variables as global variables. "vars" is deprecated, "our" should be used instead, but I'm pretty sure "vars" will still work properly.

Yes, our is definitely the preferred method for declaring globals now. But use vars will always be supported as most module writers depend on it to be backward compatible for perl before 5.8.0.
