I have N files, each of them of the form: 
line_number var1 var2 .... varN

[download]
I am reading all the files from an ARGV list 
for my $file (@files) {
while (<IN>)
$line_number= $list[0];
push @($var1{$i}), $list[1];
etc...
}
close IN;
}

I want to create for each variable an output file that would contain something like: 
for my $j (0...Nlines-1){
open(OUT, ">", "./var1.dat")
print OUT "$line_number \t $var1{file1}[$i] \t $var1{file2}[$i] \t ...
+ $var1{fileN}[$i]\n"
}
close OUT;

What is the way to write in the same line of the output file
in different columns the information for the same
variable taken from different input files?

Is there a way to open a $NEWLINE variable and keep appending
to it values from each of the input file and, after reading
from all the input files, closing the line
and then writing the line in the output file?

Thank you,
Ioana
