Hi Jeff,
i get the following error:
Use of uninitialized value in scalar chomp at xxx.pl line 12.
Use of uninitialized value in concatenation (.) or string at xxx.pl line 12.
my @out = map { chomp; my $f2 = <fh2>; chomp $f2; $_ . ' ' . $f2 . ' ' .
<$fh3> } <$fh1>;

Subject: Re: merging the columns
What if is there another file (fh3) to merge with fh1 and fh2?
How should i fix that line: my @out = map { chomp; $_ . ' ' . <$fh2> }
<$fh1>;
Hi,
Just add another filehandle in the map:
open my $fh3,'3.txt' or die $!;
my @out = map { chomp; my $f2 = <fh2>; chomp $f2; $_ . ' ' . $f2 . ' ' . <$fh3> }
<$fh1>;
didn't test it.good luck.
