    From the look of those options, I'd say they don't take any parameter. Rather, they specify actions that you want to take place, and put them on the list of @actions. Later on, you can iterate over @actions and execute each subroutine ref.

    So, if you say ./mygetopt3.pl --forms --images, you are simply specifying that you want your scipt to run its dump_forms and dump_images subroutines. From their names, those subroutines probably just dump a list of items for the user to view.

    UPDATE: I guess I should've checked first, there are much more in-depth answers in the responses to your original post.
