NAME

       Prelude::substr - Return a substring.

SYNOPSIS

       String substr( String x, Int i, Int len )

ARGUMENTS

       x The original string

       i The starting index

       len The substring length

DESCRIPTION

       Starting  at  character  i  ,  return  the  len  characters long substring. Throws an Exception if len is
       negative, or if i is out-of-bounds. In Kaya 0.2.4 and earlier, an Exception was also thrown  if  len  was
       zero. The empty string is now returned in this case.

       If the starting index is negative, then it will be counted in characters from the end of the string.

    x = "abcdef";
    s = substr(x,0,2); // "ab"
    s = substr(x,4,1); // "e"
    s = substr(x,3,10); // "def" ( len
    truncated)
    s = substr(x,-4,2); // "cd"
