in thread How to correctly use a symbolic reference to automatically generate hash names?

Thank you for your reply.

However, what I have is a set of hashes such as %wow0, %wow1,%wow2, %wow3, .... That's why I want to use a loop to handle these hashes and I need an automatic way to refer to these hashes and to update info on these hashes.

    Why on earth would you have %wow1, %wow2, and %wow3, instead of %{$wow[1]}, %{$wow[2]}, and %{$wow[3]}? In other words, instead of: 

    %wow1 = ( key => value, key => value );
%wow2 = ( key => value, key => value );

    You could have...

    @wow = (
  { key => value, key => value },
  { key => value, key => value },
);

    Which is an array of hashes, instead of a bunch of hashes loosely related by naming convention.

    I see no advantage to polluting your package global namespace with variable names that are tricky to manipulate when you could just create a single AoH structure.

    I am suggesting to not have a set of hashes named %wow0, %wow1, etc., and to instead do as I have suggested.

      you seemed suggesting to put the names of the hashes in an array then refer them the way you posted.

      is there a way to refer to hashes as I original wanted?

        Yes, use a list of hash refs would do the trick. Thank you for your suggestion.

        I still wondering how I can use soft/symbolic ref to do this.
