Does anyone out there have any clever ideas on how to get Basic 4.0
on series 200/300 machines to create and use linked lists?

I don't need to dynamically allocate and deallocate the records, but
would like to be able to have pointers associated with each one that
will point to the predecessor and successor.  In Pascal the list element
would be:

TYPE	link = ^list_element;
	datatype = {bunch of integers & booleans};

	list_element =	RECORD
			one_before : link; {points to element before this}
			data : datatype;
			one_after : link;  {points to next element}
			END;

The main goal is to be able to sort a bunch of such things in BASIC and be
able to store only as many as have been used (also in BASIC).
