in thread subtracting values from 2 hashes

Thank you Neil - I will make sure not to put so much in next time (I was afraid if I didn't, and I had made an error somewhere further up, it would have been missed). Didn't mean to overcrowd!

Please excuse my ignorance, but I have been trying to load both files into their own hashes, the two hashes are:

%max_unchanged %max_changed

Maybe there is a much simpler way.. but if I use this:

my @calc; $diff; foreach my $key (keys %max_changed) { my $diff = $max_unchanged{$key} - $max_changed{$key}; push (@calc, $diff); } print @calc, "\n";

I still get the same error.. :-s...

Re your second point, I wasn't too sure what you meant by

"Your open statements should use variables, not bare words (depreciated), and use an operator."

When you say "bare words" are you referring to an FILEHANDLE being called FILE?
Many thanks, E

    Correct, instead of using file handles as bare words (FILE) we now use normal scalars.

[choroba]: Morning!
[Corion]: Hi choroba, Discipulus!
[Corion]: Yesterday I've been mulling over how to best generate HTTP requests from permutations of values but I haven't found a nice API for passing in the "template" of the HTTP request yet. I guess I'll have to do a SoPW for that
[Corion]: The API itself will basically be my $iter = generate_http_requ ests(method => 'GET', url => '/settings/:name', headers => ???, get_params => ['foo','bar']), but I'm not sure how to parametrize values in the headers and how to specify lists of ...
[choroba]: On the other hand, lots of options to receive the requests :-)
[Corion]: ... values to be used. For example, I think for headers, one would want to have various kinds of Content-Encoding headers, but for the get_parameters one would have various kinds of Bobby Tables
[choroba]: What about [metadoc:// Algorithm::Loops]?
[Corion]: choroba: Yeah, but handing off the request to Dancer,Plack, Mojolicious,LWP is easy once I have the data filled into some structure ;))
[choroba]: Algorithm::Loops
