in thread Increaing a field size for a record

That's a funny approach, but is not very efficient, every time you're assigning to $line[$i] it rewrites all the file starting from the record $i.

Update: More efficient would be to use File::Slurp:

use strict; use warnings; use File::Slurp qw(edit_file_lines); sub fix { my @fields = split / +/; $fields[1] = sprintf "%-50s", $fields[1]; $_ = join ' ', @fields; } edit_file_lines \&fix, $file_name;
The problem is that it doesn't preserve the width of the other fields

[karlgoethebier]: Lady_Aleena: You need to jump to some conclusion
[Lady_Aleena]: And what would I rename RolePlaying/Random .pm to if I move all the RolePlaying/Random modules to just Random? Random/ Random/, maybe lowercase the file name to indicate it is a bit different? I don't know yet.
[marioroy]: What does Random do?

[Lady_Aleena]: karlgoethebeir, I finished another project tonight, making a module which printed stop printing. It was a headache and a half.
[karlgoethebier]: Lady_Aleena: Try it!
[Lady_Aleena]: marioroy, it has 3 subroutines which can be fed data to generate random things. See here.
