Concatnating strings that are too long for one line

Hi, this is a really simple question but I can't figure it out. If I want to pass a really long string to a function, it is really inconvenient to keep it all on one line since then I need to scroll horizontally to see it all.

I first tried using the + operator like:

Code:

---

function ("Long " +
    "String");

---

However apparently I can't do that.

I also tried:

Code:

---

function ("Long \
    String");

---

But for some reason the backslash seems to introduce extra characters into the string and causes my function to fail.

I'm sure there has got to be a way to do this.

Let the compiler do the concatenation for you:

Code:

---

function("Long "
        "String");

---

This relies on the fact that adjacent string literals are combined into a single string literal, and that whitespace is not significant in this context.
