You see, people think that sub( can only have three arguments. Well I'm here to prove you wrong. Here are my findings.
sub(int,int,int,int) produces an argument error.
sub(String,int,String,int) produces an argument error.
sub(cos(),!) produces a syntax error |

One or three arguments is valid for sub() – sub(X) is treated as X% or X/100 on OS versions 1.15 and later, and then you have the documented use. Of course having any other number of arguments would give an argument error. I don't see the revelation here. In fact, choosing 2:Goto from the third line shows that there's a problem associated with cos(), which pretty much says nothing about the behavior of sub().
Going further, if you meant that we should provide a value for cos(), and yet see a syntax error anyway, then that's because of the order of operations: the interpreter will attempt "comma factorial" inside the function, which will obviously result in a syntax error. This can even be seen in tan(1,sin(270[font="times new roman"]°)!) – the sin() will come out to be negative one, and then when factorial is employed, it'll give a domain error. Using sin(90[font="times new roman"]°)! instead means the interpreter will successfully evaluate the argument, but then it realizes that it doesn't belong to the function. Make sense?
The one thing that I'm confused about is what you mean by "scroll the homescreen" in the title.

Haha, people who are learning the language will try it and end up disappointed! How hilarious?
*ahem* I guess it's just not my style of humor.
