What I am trying to do is convert the verticle bags mod from a 35,35 size to a 24,24 size and I understand the lower half of the code but I am not sure what the above settings are doing. Can anyone explain or point me to a location that explains it? Thanks!

P.S.

None of the above has been modified yet it is still original code from Weegie's Vert Bag Mod.
