LlDeleteSubString

Returns a string that is the result of removing characters from src from start to end.

start & end support negative indexes.
It removes both start and end as a matter of course.

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 ex = "abcdefghi";
        llDeleteSubString(ex, 4, 7); //Incorrect!
    }
}

 
default
{
    state_entry()
    {
        string ex = "abcdefghi";
        ex = llDeleteSubString(ex, 4, 7); //Correct
        llSay(0, ex); //Would say "abcdi"
    }
}
 

 
//-- special case
default
{
    state_entry()
    {
        string ex = "abcdefghi";
        llSay( 0, llDeleteSubString(ex, 4, 7) ); //Would say "abcdi"
        //-- acceptable if you do NOT want to change the contents of 'ex', only the output
    }
