Types?

-----------------------------------

ok I know how to use types fairly well but I am running into one main issue and I'm not sure if its resolvable

heres what I want to do

type node :
record
x : int
y : int
parent : node
end record


Is it possible to do this? If so what code do I need to add?

Are you trying to make a linked list?

I think for this you have to use another construction, called collections. There are examples in the [url=http://compsci.ca/v3/viewtopic.php?t=9284]linked list tutorial.

I think you can still use type you just need a pointer :
type node : 
   record 
      x : int 
      y : int 
      parent : ^node 
   end record

But I no longer have Turing so I'm not sure. :)

Yes that is correct, to declare a node you would have to do

var moo : ^node
% Create a  new node and assign the memmory to the pointer
new moo


At the end 

% Free the memmory assigned
free moo
