To implement inheritance do:

1) generate a base-class from a suitable control-file
2) generate a derived class from another control-file
   put into the header section:

	package Derived_Class;
	use Base_Class;
	@ISA=("Base_Class");

4) edit the derived class; in the new() method of your derived class
   you'll find right after the blessing

	#$self->inherit_from($self->your_base::new());

   remove the # and replace the term 'your_base' by the name of your
   derived-class. copy and adapt this line if you inherit from several
   base classes. make sure to put these in the @ISA as well. result:


	$self->inherit_from($self->Base_Class::new());


   this approach is unusual compared to what you can find in the perl
   literature so far. it is necessary because the classes, which
   classgen generates, incorporate instance variables $x,%x or @x.
   so you have to make sure memory is allocated for them through the
   call to new() of the base class. inherit_from() will take care,
   that those variables will be accessible through the base classes
   methods.

WARNING:
   classgen has not been designed to handle multiple inheritances
   (though it works even then).

   it is up to you to ensure that all variables will be unique.
   classgen works fine for simple inheritance, which will suffice in
   most cases.


5) edit more specific functions to the derived class


Enjoy.
