When perl comes out with errors like this:
Use of uninitialized value in concatenation (.) or string at NQII.pl line 18, <STDIN> line 2.
Argument "" isn't numeric in numeric ne (!=) at NQII.pl line 342, <STDIN> line 2.
Argument "neopets.co m/hi.phtml" isn't numeric in numeric ne (!=) at NQII.pl line 342, <STDIN> line 2.
Argument "POST" isn't numeric in numeric eq (==) at NQII.pl line 343, <STDIN> line 2.
Argument "POST" isn't numeric in numeric eq (==) at NQII.pl line 343, <STDIN> line 2.
Use of uninitialized value in concatenation (.) or string at NQII.pl line 355, <STDIN> line 2.
Use of uninitialized value in pattern match (m//) at NQII.pl line 391, <sock> line 22.
Does that make it slower? And any tips for getting rid of these errors?

Well, troubleshooting Perl is typically a process of elimination (IMHO). I usually start with the most obvious error, which in this case would be "Use of uninitialized value in concatenation (.) or string at NQII.pl line 18, <STDIN> line 2".
This tells me that in your script, you have a variable being referenced that is not set when it is used. This could be caused by any number of situations, but for me, it has happened when the variable was out of scope.
If you posted your code here, we could help you troubleshoot it and guide you to getting it working.

It works fine actually - with no errors to stop it. Though i was wondering if these little errors make it slower? Or do they have no affect at all on the speed?

these are not errors, they are warnings. I would certainly try and fix them and see if it helps increase the execution time of your script. Once they are all fixed you can disable warnings and see if that also helps.

I don't particularly want to post the whole script here, think i could PM you it?

Please do not PM me your script. Maybe someone else will take a look at your code and help you debug it, but I don't want to.

Fair enough.

Hello,
Is it possible if a boolean was initialized or not? For other types of

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
