You can define package-scope variables using something like:
[code]
# Define a variable:
our $pi = 3.141592;
our $num_days_in_year = 365;
# And then wherever:
sub hello
{
my $r = shift;
print "You have a circle with a circumeference of ", (2 * $::pi * $r),
"\n";
}
[/code]
Even modules (that can be loaded using "use", "require", etc.) can define such
package scope variables.
