in reply to How can I declare constants?

If you don't mind that it can be changed, you can simply declare your constants as follows:

# Constants used throughout the program:
my $number_of_pages = 3;

If you are really paranoid and don't want your constants to be changeable, use the constant pragma:

use constant NUMBER_OF_PAGES => 3;

    Thank you. I used this pragma already but had the problems mentioned in the bugs section (brewordsm, sub calls). Does there exist any other alternative (no my or our declaration)?

      You can decalare a sub routine... 
      use strict;
use warnings;

sub PI () {3.14}
print PI;

      still not sure what you've got against 'my' though

      No. The only bareword-"problem" in the documentation also has a solution mentioned with it. Did you try that solution? What part of that solution did not work for you? Can you show some code that demonstrates how you followed the documentation but still got the wrong behaviour?
