Re^8: Adding a TAB after a certain ammount of characters

Almost. Use lexical file handles and three argument open:

open my $FILE, '<', 'file1.txt' or die "Cannot open file1.txt: $!";
[download]

To iterate over the lines of the file, use the diamond operator in a while loop:

while (my $text = <$FILE>) {
    chomp $text;
    my @cums = (0);
    # ...
}
[download]

You can define the @offs outside the loop because they never change.

Thanks everyone, I was able to complete it, here is the the final product `#!/usr/local/bin/perl open my $FILE, '<', 'rapipago.txt' or die "Cannot open file1.txt: $!"; use strict; use warnings; use feature 'say'; while (my $text = <$FILE>) { chomp $text; my @cums = (0); my @offs = ( 17, 6, 31, 3, 3 ); my @cums = ( 0 ); push @cums, $_ + $cums[ -1 ] for @offs; substr $text, $_, 0, q{-} for reverse @cums[ 1 .. $#cums ]; say $text; }` [download] Now I have another question, is there a way that instead of printing with say, the results prints on another file, or the program modifies my first file with the result?

#!/usr/local/bin/perl 
open my $FILE, '<', 'rapipago.txt' or die "Cannot open file1.txt: $!";
use strict;

Now I have another question, is there a way that instead of printing with say, the results prints on another file, or the program modifies my first file with the result?
