Re^2: Most Annoying Error : Use of uninitialized value in concatenation (.) or string at C:\Perl\O

I didn't read your post

Perhaps you should have.

its not an error. It's a warning!

That's right. It's a warning that is telling the OP that something might be wrong.

By telling him to blindly remove the warning, you are removing the only clue he might have to find out why the program did not behave as expected.

The right thing to do in these cases is to either inspect the data or apply tome sanitizing methods to make the data consistent.

Did you notice that I wrote "if you're really sure 'bout what you're doing" in strong tags?!? I have strict and warnings turned on all the time. But that's the single warning that every now and again can be safely turned off locally.

Did you also notice that I specifically instructed him to do that in a lexical scope with a code sample suggesting to do that around a single line of code?
