Of course this works. arg is an array. arg[0], arg[1], etc. are scalars (numbers).
You can stuff an array and then cherry-pick numbers from it, no problem. One thing to keep in mind though is that if you are using an index to do your cherry picking, (e.g. arg[ndx] ) the index needs to be always defined at the point you are using it.
Further, if you are looping over that index, then within the loop all the unadorned array names you use will be expected to have subscripts. IOW, you can't write "naked" array code inside a for loop (though you can pass arrays to functions and get them back).
The way I've come to look at it is that when I have a loop in my code( any loop, not just a 0 -> (BarCount - 1) loop ), I am in a "loop environment" for the duration of the loop, and must alter my authorship accordingly.
