Call a prg within define class to add additional function or proce

I want to know whether it is possible to call a program within define class
to add additional function or procedure:

test.prg contains:

Define class test as custom

procedure x
..
..
endproc

if something is true
do add_procedure in addtoclass.prg
endif

Enddefine

addtoclass.prg contains something like this:

procedure y
..
..
endproc

You can only do this with a builder.
A builder may use commands like
oClass.READMETHOD and oClass.WRITEMETHOD.

But a Builder works on a class (oClass) that
isn't instanciated as an object, it works on the
source code of the class.

I think this is especially not possible with prg
classes, but I haven't tried that.

Ehy would wou want that? You can extend
or overload behaviour nicely with BindEvent
or RaiseEvent and another object.

Bye, Olaf.
