Well, You can either compare it by hand or use a module. Use search.cpan.org to find modules that might be useful. A search for 'Arrays' brought me Set::Array which as the methods for at, length, intersection, and union. You can use length and union to find out how many elements in each array are different. If you want to know how 'close' each A is to each other, you probably need to compare each element in each manually. -- milki _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
