Hello QuillMeantTen,

As usual, I'm looking for ways to get better so constructive criticism is welcome.

I can’t try out your code, as I don’t currently have pdflatex installed. But I notice that you call open and close without testing for failure. It’s good practice to either test each call explicitly:

open(my $tombolatex, '>', 'int.tex')
    or die "Cannot open file 'int.tex' for writing: $!";
[download]

or to put:

use autodie;
[download]

at the head of your script. See autodie.

Hope that helps,
