Use the 'use warnings;' pragma in your program instead of '-w' on the first line. That way, you can control which messages are issued. I do not know if it is possible to get rid of the warnings you are seeing. I do not use the 'say' command, but prefer print, and use one of the other techniques I listed. See 'perldoc use warnings' and 'perldoc perllexwarn' for more details about 'use warnings'. > The code is last in this text.
