It's saying that these variables haven't been defined. E.g. they haven't been declared local variables with 'my' such as my $version; Or you haven't declared them as Global with 'our' such as our $version; Note that 'our' is only in Perl 5.8 and up. Previously Globals had to be declared with use vars, such as use vars qw( $version ); You can still 'use vars' post Perl 5.8, some people prefer it to 'our' and it's good for backwards compatibility (and keeping all your globals listed in one place) Lyle _______________________________________________ ActivePerl mailing list ActivePerl@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
