Answer #2: If the code will always be the same, and
only the values of some variables will be different, you
can make anonymous functions like this:
sub create_subroutine_to_return_constant {
my ($constant) = @_;
my $newsub = sub { return $constant };
return $newsub;
}
Then you call it using the
-> notation:
my $PI = create_subroutine_to_return_constant(3);
$z = $PI->(); # returns 3
This technique is a lot more interesting than the example I showed.
But I didn't want to give too much information at once.
Perhaps you could say a little more about what you are trying to accomplish
here.
