Re: Help needed understanding global variables in Perl
in thread Help needed understanding global variables in Perl
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:
$main::f = 42; print "The value is $main::f\n";
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.
