1. pointer question
is it possible to have pointers to functions or procedure
like in C/C++??
I know about the routine_id function but I need a less
complicated way of executing functions and procedures
for OOP techniques I'm creating.

The answer is there is no easy way.

Not to my knowledge. I would be cool if we could say:
procedure a()
end procedure
procedure b -- Declare variable of type procedure
b = a
b()
I don't think RDS's Euphoria will ever support it. That kind of syntax
makes much more sense than routine_id.

What precisely is the reason you need it ?
First of all...
my_object = call_func (my_object[MY_METHOD], {my_object})
Isn't that complicated. Secondly:
my_object = my_method (my_object)
works as well. Or is the namespace the issue you're dealing with ?
If so the above won't help much, since the constant MY_METHOD can't be a
constant if you need mutual recursion between the
objects. The constants of at least one of the object definitions should then be
integers, and assigned a value at a latter
stage.

No, the only thing you can have in Euphoria is the routine ID of a =
function or procedure.
Have you checked out the Euphoria web page? They have a number of =
packages that aid in OOP development (including mine... 
). From what =
I can tell, they all still have to use routine_id in some fashion to get =
what you want done, but at least you might find the kind of functions =
you need already written.
