How does a macro determine inventory slot versus bag slot

[McSpriest]

I have a macro question I've been wondering about for those of you out there.

how does it identify bag spot vs. inventory spot

like for example:
/use 1 4
uses the fourth item in my first bag (non-backpack) or equips it if its equitable

versus
/use 1
which activates my helm if it has a use (like headless horseman's hat)

and obviously
/use 14 activates your second trinket

is it that space in there that identifies if its bag or inventory?
like is the fact that there are two numbers allowing it to recognize the difference?
just curious that's all

I'd assume so, yes. A simple match of:

local input = "1 4"
local bag,slot = input:match("(%d+) (%d+)")
if bag and slot then
    -- do something
else
    local inv = input:match("%d+")
    if inv then
        -- do something else
    end
end

(pseudo-code, obviously)
