Just to make things clear (well, it had me stumped for awhile), calin means replacing the () in the values of your page hashes by []. That way, you're assigning an anonymous array to the value of the hash, instead of a list, as you are currently doing.

BTW, the @AoH assignment throws a warning:

Odd number of elements in anonymous hash at aoh.pl line 21.

That is because of the parentheses instead of square brackets.

As to your second question: it's an array of hashes one of whose values is an array of hashes. So, in a sense, it is a AoHoAoH :)

    Thanks robartes, for the explanation. I had changed all the parens to brackets and got warnings (after you reminded me to turn those on, duh). Anyway got it to work using the brackets as you indicated.

[shmem]: wait, what? you want that person to read the documentation for you?
[Lady_Aleena]: I might have to go with options instead of a straight list.
[Discipulus]: if more than 3 go for named variables LA
[Lady_Aleena]: Discipulus, it is at 2 now, but with what I am thinking about, it could go to 3. However, only 1 is needed. The second and third are optional.
[shmem]: straight list or named parameters - that depends on whether (and how many) optional arguments you have
[Discipulus]: if so a plain list is ok, imho
[Lady_Aleena]: shmem, I already have the plugin installed, just not active.
[shmem]: if you have 1 optional argument, place that at the end of the list. If you have more, go for named parameters.
[Lady_Aleena]: 1 manditory, 2 optional.
[Discipulus]: my ($need,$opta,$optb ) = @_; .. if $opta..
