$pack([bank,]slot,<option>): returns pack information.
<option> can be: name, combine, open, size, weight, slots, space, empty
First how many bank slots are there and how are they numbered? I don't have access to game right now from memory...
0-5 9-13
1-6 10-14
2-7 11-15
3-8 12-16
17-18
17 and 18 are the two shared slots? Not sure on any of this just guessing.
Given that the 0 inventory slot in the bank has a container of some kind I it…
/varset Pack1 $pack (bank,0,open)
Would I get TRUE or FALSE if that container were open or closed respectively?
