Yes, "index" is a common term for the consecutive numbers that the 
"slots" of a list or array are addressed with. Lua by convention starts 
counting at 1, most other programming languages start at 0.

If you don't know where in the list the object is, then you just search 
for it. The shortest way of doing that I can find right now is

index = table.foreachi(state.inventory, function(i, v) if v == "TVCable" 
then return i end end)

although you can also spell it out as

for i = 1, table.getn(state.inventory) do
   if state.inventory[i] == "TVCable" then
     index = i
     break
   end
end

Yes, the inventory keeps objects in the order they were picked up. If 
you don't like that and would rather have them e.g. in a fixed order, 
you need to change the inventory code.
