Re: RegExp eating my $1by busunsl (Vicar)

I haven't run your program yet, but a few things struck my eyes:
Regexes are not always better/faster than anything else, in this case the substr function might be better.
my $ffc = substr($line, 0, 6);
If you want to assign the captured part of a match to a variable, you can do it like this:
my ($foo) = $bar =~ /(...)/;
Mind the parenthesises around $foo, the match returns a list of values.
Your loop through the keys of %files is uneccessary, use the exists function.
Perhaps you might be able to streamline your program a bit, so that the error is more obvious.
