Thank you for your response...
So I must change it to something like this? 
%dict =(
     label => ('label 1', 'label 2')
)

[download]

What's the pro's of doing it this way?

    That should be:

    %dict =(
     label => ['label 1', 'label 2']
)

    [download]

    Using [ .. ] to create an anonymous array.

    The advantage is that array access is much faster than hash access.

    A good approch would be to code up both alternatives and benchmark them.

      Slap me with a wet micro$oft t-shirt for not using [ .. ]
      Had a brain fart for a second using ( .. )

      There's not much difference in the bench mark, but i suppose the size of the array makes a difference... and i predict it will become rather large as my program progresses...

    as said above, an array would be faster, but I mentioned this mainly in a "right tool for the job" type way.

    If you are accessing something based on a numeric index, you might as well be using an array. It's what they were designed for. :)
