in reply to I'm in trouble with Perl's OO programming

Inheritance does not work when you access WatchLog and SendEmail as subroutines. In fact for the sake of symmetry I would use a method invokation for AddLocalTime or at least change the name to _AddLocalTime to indicate that it is a local class method intended for use within the class.

use base A .... sub Schedule { my ($self) = @_; $self->addTab(_AddLocalTime); $self->addTab($self->WatchLog); $self->addTab($self->SendEmail); } sub _AddLocalTime { }
