Yes, one of my questions is indeed that.
But what is the standard way of declaring global variables in Perl? With our? With use vars (which now I know that is obsoleted)? With anything else? The problem is that even if I don't declare and define anything, I can get rid of warnings just by fully qualifying the variables. In other words, the script below seems to be entirely legal:
The problem is that Programming Perl, 2nd ed. (the one that I have) is not very specific about the subject and I've read already quite a bit of the book (chapters 1, 2, 4, 5 and part of 6). I don't intent on using global variables, but I feel bad for having trouble not understanding such elementary subjects after reading a fair amount of the documentation.
