Re^2: what is difference between chr and oct?

Thanks for your reply. You may see above message as a warning other than error, but as matter of fact, it just because chr treat any string as number 0 if closed warning pragma. That means the output will be totally wrong:

#wrong output:
xyf@andy:~$ perl tt.pl
        xyf@andy:~$ 

# right output:
xyf@andy:~$ perl tt.pl
f e e l i n g   lxyf@andy:~$
