Great series of articles for beginners in Perl.
Is Perl IV out yet? What are some good online refs.
(besides those listed) that might have downloadable
manuals/books on Perl Programming etc. Thanks.

Please help me. I need to do this using Perl.

# 4. Write a program that creates an array of values.
# Use a hash to determine if there are any duplicate values in the array.

@number = ( 12, 23, 34, 45, 23, 34);
foreach (@number)
for (keys %hash){
if($hash {$_} -1)
print "The number is repeated $hash \n";

foreach(keys %hash){
print "$number \n";
