[Coco] Basic09 Linked Lists

[Aaron]

Hi all,

I found a snippet of code for a linked list, which is essentially an array
of `type`s:

TYPE link_pointers = fwd,back: INTEGER
TYPE element = data: STRING[64]; ptr: link_pointers
DIM list(100): element

Is this the best way to make a linked list in Basic09?  Or is there a
better implementation out there?  Ideally, I'd love to use it without
having to pre-define the length of the array.  But, unless things have
changed in the last 20 years, I'm aware of the limitations of Basic09.  :)

Thanks.
