in thread Reading Multiple Input Files

Good call! I used 

for ($i=0; $i<$Num_of_Files; $i++) {
open(Read, $file[$i]);
@Read = <Read>; 
...}

[download]

I used this instead of for my $file1 (@filenames) { ... } so I could assign a name for each of the output files.

A coworker suggested that I use use strict but I don't see the usefulness of this. Why do you use it?

    I had a node around here about why to use strict....

    Ah, here it is -- On Commenting Out 'use strict;' .... It's a tad dusty, I wrote it three or four jobs back, but it is still applicable.

    Ouch, C-style for loops in Perl.

    A more Perlish approach is

    while ( my ($index, $file) = each @filenames) {... }

    No need to calculate the number of files, you don't need to use indexes to access the filename and you still have the $index variable to use in composing the output filenames.

        Oops, sorry indeed. I forgot to mention I run everything under "use Modern::Perl;";
