Dealing with Tabs

I have a string of integers returned from llHttpRequest that is separated by Tabs.

1<tab>2<tab>3....

The string can be up to 240 chars long (counting <tab> as 1 char).

I need to retrieve these values sequentially one at a time.

I would like to do this:

            integer index = llSubStringIndex(stringWithTabs, "\t");
            val = (integer)llGetSubString(stringWithTabs, 0, index - 1);
            stringWithTabs= llDeleteSubString(stringWithTabs, 0, index);

But the "\t" reference is obviously invalid.

Due to the string size limits on llEscapeURL() my string is too long.
Splitting it up is a bit of challenge since I can't search on the tab char. Though I may end up fudging a function for this.

Is there an easier way to reference special chars that I am missing?

Well, my first answer would be to change your output delimiter. I guess that's not an option, though.

You can access any special character you want in a script by using llUnescapeURL(). I believe something like llUnescapeURL("%09" might be what you want, but I may have the number wrong. It turns out that using llUnescapeURL like this (or llBase64ToInteger) is the only way to get at extended ascii characters in a script... trying to include them in a string literal makes the compiler puke.
