@ -181,11 +181,14 @@ Here is a more detailed description of each type:
second-to-last character, etc. Here are a few examples::
local orig = "0123456789";
local second_char = orig[1];
local last_char = orig[-1];
local first_two_chars = orig[:2];
local last_two_chars = orig[8:];
local no_first_and_last = orig[1:9];
local second_char = orig[1]; # "1"
local last_char = orig[-1]; # "9"
local first_two_chars = orig[:2]; # "01"
local last_two_chars = orig[8:]; # "89"
local no_first_and_last = orig[1:9]; # "12345678"
local no_first = orig[1:]; # "123456789"
local no_last = orig[:-1]; # "012345678"
local copy_orig = orig[:]; # "0123456789"
Note that the subscript operator cannot be used to modify a string (i.e.,
it cannot be on the left side of an assignment operator).
