Hi,
you're welcome.
The ctrl+o thing: hold ctrl, and press o (thats an o not a zero)
It's called a "shift in" and is represented by ascii number 15. You can see it also by doing //echo -a $chr(15). In mIRC, ctrl+o inserts a control code for plain text, but since you're tokenizing on that string, it has no meaning then, and is only used as a means to achieve something.
/help control codes
The reason ctrl+o is good, is because the odds that you will use them in a string, or in any incoming string is almost nihil, unlike a space $chr(32), so that you'll be sure that the tokenized params are filled with the right contents. I'd even prefer using $lf or $cr, but then you need the $+ identifiers to paste text together, which you don't with the shift in. Note that there are more chars that can be used, I just happen to use this one often, hehe. This probably doesn't make much sense to you, so just consider it as a handy trick
Btw if you're interested to see the ASCII chars with their according decimal values:
