Question about packets

[Anthony]

So I am starting to go through, and using Williams Enum tutorial, changing all my packets. I remember DFA mentioning about the & SEP_CHAR & END_CHAR thing. Nobody really said anything about it and not that I don't trust his judgment I would just like another opinion before I go removing them all.

So can I remove that extra & SEP_CHAR without damaging anything? Or is there a specific reason it is there?
