Hi,
Please run perldoc Carp at your command prompt.
As you can see, cluck, longmess and shortmess not exported by default.
NAME
Carp - alternative warn and die for modules
SYNOPSIS
use Carp;
# warn user (from perspective of caller)
carp "string trimmed to 80 chars";
# die of errors (from perspective of caller)
croak "We're outta here!";
# die of errors with stack backtrace
confess "not implemented";
# cluck, longmess and shortmess not exported by default
use Carp qw(cluck longmess shortmess);
cluck "This is how we got here!";
$long_message = longmess( "message from cluck() or confess()" );
$short_message = shortmess( "message from carp() or croak()" );

Hi Krzysztof
If that was the case , using the subs inside Carp should not show any
error.
Bu I was not able to use cluck without using qw and was able to use
croak and confess without the qw.
Don't get it
thanks
