3/17    In Perl, when I "use strict;", how do I declare a global array
        or global hash? use vars qw (@ASSOC, %KEYHASH); doesn't work...
        \_ At the start you can declare "my @array", and everything in that
           scope or below will see it. --scotsman
        \_ It should be:
           use vars qw(@ASSOC %KEYHASH);
           (no comma)
           I believe in perl >= 5.6 you can say:
           our (@ASSOC, %KEYHASH);  --dbushong
