string.sub (s, i [, j]) |
Returns the substring of s that
starts at i and continues until j;
i and j can be negative.
If j is absent, then it is assumed to be equal to -1
(which is the same as the string length).
In particular,
the call string.sub(s,1,j) returns a prefix of s
with length j,
and string.sub(s, -i) returns a suffix of s
with length i. |
