Hi All, I am wondering if there is a difference between: The last one I believe I know the answer, empty string still defined, but I sure wanna clear view..:-) PS: will use strict / warning will make a difference ?
do_somthing if ($legend); or do_something if (defined($legend)); or do_something if ($legend == ""); another question: is there a difference between @arr = (); And @arr; Since both of them showed nothing when trying to do this: print "Yea" if (@arr); thanks Chanan _______________________________________________ Perl mailing list [email protected] http://perl.org.il/mailman/listinfo/perl
