Not entirely on topic, but have you considered using one of the Getopt modules? It is usually the best way to go when dealing with command line flags. Personally, I recommend Getopt::Long.

There are sundry examples of Getopt::Long examples in The Monastery's archives. Supersearch if you need help. :)

And you didn't even know bears could type.

[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..
