    When I do that I get the error message:"Cant use string ("...") as an ARRAY ref while strict refs in use.

    anyway I updated the post to give more insight into the question.

      You were very vague about your input format. I assumed you meant:

      my %checkfrom = ( Meat => [qw( Fish Apple Pork Bacon )], Fruit => [qw( Apple Pie Orange Beef )], );
