Line of JASS

Okay, I was studying a JASS map learning tidbits, and then I got to this line:
I pretty much understand it except for what S2I means.

It's a conversion of "String 2 integer"

Thank you.

That line is legal syntax?

i presume its part of a bigger line. Else the map wouldnt work.

Oh, yeah, that too. I was referring to S2I( integer ).

that line is completelly senseless I hope you invented it up in an attempt to make your post seem more credible

udg_ep[( S2I(( 2 + 2 )) - 9 )] ) )
S2I takes a string returns an integer, 2+2 is not a string. There are also numerous extra parens.

Especially since that isn't even a line, it would have to be a part of a line.

You can just ask what S2I means.

Yeah, if you just found that in a tutorial, I would ditch that tutorial straightaway :P

this line is totally fucked, who gave u this line man?

No one, I was reading through JASS in a map and came across that, and apparently that line does work because nothing's wrong in-game.

What map was that?
Oh, and btw, wouldn't it be "Thee who calls one an idiot art an idiot thyself"

That line does nothing. I'm suprised it even compiles.
