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"
