Possible error in help file?

Under TIA registers, NUSIZ0, NUSIZ1 it says this:

 

$x0 one copy of player and missile

$x1 two close copies of player and missile

$x2 two medium copies of player and missile

$x3 three close copies of player and missile

$x4 two wide copies of player and missile

$x5 double-sized player

$x6 three medium copies of player and missile

$x7 quad-sized player

 

But when I try to compile something like that it won't work, but if I put a 0 in place of that x, it works. What the heck is going on?

The x is just a placeholder, like a variable, meaning it can contain any value shown; the author split the explanations up into 1st digit options and 2nd digit options, replacing the one NOT being discussed in each part with an 'x', that dosn't mean you can use an x in your program, it just means "x is whatever number you choose from the other part of this explanation."

 

Sorry, I'm not good at explaining things in short easy to understand sentences.

Well, I understood that. Thanks for clearing that up.
