1- Thanks for posting with a descriptive subjects:)
2- $_ is the default perl variable, when you don't specify one and you
cann a while, foreach, etc, it has that variable in the $_. Right after
declaring a variable, $_ stores that variable.
the best if you don't want to play with $_ yet, declare a variable to
hold the data
you should always add use strict; to the top of you script, therefore
you will have to declare @words using my
print "please enter a word\n"; #neter is not english :)
chomp (my @words = <STDIN>);
foreach my $oneword (@words){
printf "%20s\n", $oneword; #puts each value of the @word in
$oneword.
}
(untested)
