[Chicago-talk] Scalar question?

[Richard Reina]

my $scalar = "whisky";

If this gives me the last 3 characters of the string
"whisky":

my $s = substr(3,3,$scalar); 

How can I get the last three letters of any string
regardless of the strings length (given that the
string will be atleast three characters long)?

Any help would be graetly appreciated.

Thanks
