LlGetSubString

Returns a string that is the substring of src from start to end, leaving the original string intact.

Mentally first translate any negative indexes into positive indexes

Positive indexes past the length (after the last index), or negative indexes past the beginning (before the first index) are valid. The effects are predictable, the entries are treated as if they were there but were removed just before output.

See negative indexes for more information.

    state_entry()
    {
        string word = "Hello!";
        llOwnerSay(llGetSubString(word, 0, 0));
        // Object: H
        llOwnerSay(llGetSubString(word, -1, -1));
        // Object: !
        llOwnerSay(llGetSubString(word, 2, 3));
        // Object: ll
    }
}
 

The counting of the characters starts at 0. Using 0,0 as start and end positions would return the first character only. Using negative numbers causes backwards counting, so -1 is shortform for the last character in a string. Ergo, using 0, -1 as start and end positions would return the entire string.

To ascertain how long a string is, use llStringLength.
