Dear Perl Monks,

I'm new to Perl and have a naive question about a small program.

If I run the following program with data embeded in the program, the output is fine.

my $horiz_data = <<"HORIZ" ;
||||01/01/2007|01/02/2007|01/03/2007|06/29/2007|
|JOHN DOE|Event1|SUB|PARTY|CLASS|WORK|VACATION|
|JOHN D0E|Event2|SUB|CLASS|CLASS|WORK|PARTY|
|JANE DOE|Event1|SUB|PARTY|CLASS|WORK|VACATION|
|JANE DOE|Event2|SUB|CLASS|CLASS|WORK|PARTY|
HORIZ

my @horiz = split "\n", $horiz_data;

my @dates = split '\|', shift @horiz;

shift @dates;
shift @dates;
shift @dates;
shift @dates;

for my $line (@horiz) {

my @flds = split '\|', $line;
shift @flds;
my $name = shift @flds;
my $event = shift @flds;
my $sub = shift @flds;

my @dates_copy = @dates;
for my $date (@dates_copy) {
print "|$name|$date|$event|$sub|",shift(@flds),"|\n";
}

} # for $line

But if I make a little change to have the program read the same data from the data file. The last line of output is broken to two lines.

my @horiz = <STDIN>;

my @dates = split '\|', shift @horiz;

shift @dates;
shift @dates;
shift @dates;
shift @dates;

for my $line (@horiz) {

my @flds = split '\|', $line;
shift @flds;
my $name = shift @flds;
my $event = shift @flds;
my $sub = shift @flds;

my @dates_copy = @dates;
for my $date (@dates_copy) {
print "|$name|$date|$event|$sub|",shift(@flds),"|\n";
}

} # for $line

Can you please advice what the problem is? Thanks.
