Thanks. I guess that would work. I think I like my simple list_diff([EMAIL PROTECTED], [EMAIL PROTECTED]) function better. I did not go with List::Compare because it is too long winded and I don't need any other part of it's functionality yet (although i may ) . So far , I use the display_columns_minus(@b) method the most. It is easiest to type and remember. The list_diff method is useful too. The display_columns(-minus => @b) api makes it too hard to override the display_columns and I do not use it despite my initial excitement :) . It would be good if the sub did not define the list it is returning. IE, if i had the list in a config var somewhere and just used the method to access it and various subsets of it. cheers "Get those items which appear (at least once) only in the first list."
