Re: Help in putting "$" as part of output

Please change:

open(F,">$filename.inp");

to

open my $F, ">", "$filename.inp";

Then change all subsequent references from F to $F.

See open for more details. That won't fix your current issue, but it'll level up your code and beginner status.

use autodie;

I was trying to be semantically equivalent to the OP. Sure, I could have said open(F,">$filename.inp") or die;, but my intent was not to advocate for an error handling strategy one way or another. I've also never had a need to use autodie, so it's not a go-to of mine. I know people who swear by it and those who hate it. Me, I am indifferent. And lazy.
