Hi bandya,

It looks as though your fieldnames have newlines embedded at the end.

If this is the case,what you want to do is

for (@fieldname){
    chomp; # see perldoc -f chomp
    print "$_\t"; 
}

though it would be better to chomp fieldname when you put it into @fieldname.

Alternatively, combine the chomp with allolex's join method, and use

hope this helps

Assuming an array @fieldname,

print join("\t",@fieldname);

Update: I should probably add that your C-style for loop is very ugly in Perl. Have a look at the functions for, foreach, while in perldoc. :)

The first print statement prints one element, with a newline. The second statement prints a single tab on the new line. On the next iteration, the next field is printed on that same new line, and another newline is output. Then another tab, from the next new line, and so on. So you're always starting over with a new line, and always tabbing from the beginning of that new line.

You should be chomping the data. If you don't really care or need for it to have newline characters in it, chomp them as the data is slurped into the array.

Try this:

my @array;
while ( my $line = <STDIN> ) {
    chomp $line;
    push @array, $line;
}
#.... later on...
foreach ( @array ) {
    print "$_\t";
}

A slightly more obfuscated way of printing the list, while avoiding using a foreach (or for) loop could be:

{
    local $, = "\t";
    print @array, "\n";
}

The preceeding example sets the output field separator, contained in $, to the tab character. Just don't forget to switch it back or you'll have a mess in other places in the program.

Hope this helps...

UPDATE: Egads, too early in the morning. Code has been fixed. Thanks for the head's up. Duh!

Hi davido,

This is wrong in (at least) 2 regards. Firstly, the syntax is wrong in the while loop. What you needed was

while (my $line =  <STDIN> ) {

Secondly, chomp does not return what you think it does. It returns the number of characters it removes, in your case 1 for each iteration. So your final result will be like

1    1    1

Hope this helps

Wiping sleepy sand out of eyes..... Thanks for the head's up. I've fixed what should have been simple code. That will teach me to cut the 'test it first' corner. ;)

By the way, you can see my use of chomp's seldom-used return value here: Chomped JAPH.

Thanks again.

@field = qw(look at me now);
@field2 = qw(this is so neat);

local($\, $,) = ("\n", "\t");
print @field;    # first row
print @field2;   # second row

look    at    me    now
this    is    so    neat

About your original problem: I think your fields data ends in newlines.
