## SYNOPSIS

string.sub(s,i[,j])

## DESCRIPTION

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.

## RETURN VALUE

Returns a string.
