I am trying to put a simple program together to send reminder emails to people at work about one of our QA procedures. I have pieced the following code together from the SAMS book 'Teach Yourself Perl in 24 Hours' but it fails at the print command. Can anyone enlighten me as to why? As far as I can tell I have copied the code from the book exactly. 
#!/usr/bin/perl -w
use strict;

#
# Subroutine for reading prev.txt into an array
#

sub readdata {
        open (PH, "prev.txt") || die "Cannot open prev.txt: $!";
        my(@DATA)=<PH>;
        chomp @DATA;
        close (PH);
        return(@DATA);
}

#
# Test reading of prev.txt by printing the array
#

print "@DATA";

#
# Subroutine for writing array into prev.txt
#

sub writedata {
        my(@DATA)=@_;
        open (PH, ">prev.txt") || die "Cannot open prev.txt: $!";
        foreach(@DATA) {
                print PH "$_\n";
        }
        close (PH);
}
