String
 

String to UPPER CASE.
String to lower case.

Fun.

str2low(string) -- returns string.
str2up(string) -- returns string.

Why make them global functions?

Should be a part of the string object.

string.lower()
string.upper()

Or

NPC Code:

---

string.toupper()

string.tolower()

---

=)
But I agree, these should be added.
I like the 'to' in front. ^^

Because I just wanted to tell what should be added... Not do anything more. (And I was thinking of how to do it. It sucks that we can't have our own object functions we can make... Or can we?)

...?

public function() {}

Unless you mean extending Graal types.

Yes he probably meant that.
