Re: a problem about function returning point

Thank u Klaus:

Thank u for your point out my program line by line, thank you:)
This program be wroten three years before when i first met
Perl. So, it's be designed so complex that not necessary. And without
using strict and warnings.
Today i add 'using strict' and 'using warnings' and reduced
complex, the problem solved.
Thank u.

Like with every strange problem in Perl, first try the following, put

use strict;
use warnings;
