Ack! pffft!

Everything in C is really just an analogue for an assembly programming technique
If you want to use a linked list, go ahead, but if you want an array use an
array.  A typical assembly array is:

	DS 20 ;reserve 20 words for 20 array items

Might be "BSS."  I get Z80 and 68000 compiler pseudo ops mixed up.  To access 
the array you can use indexed addressing, or just about anything else you like.
(eg:
	MoveQ #0,D0
	Lea   TableLabel,A0
	Move  0(A0,D0),D1
) 
Fix the code to work.  (As I said 68000 assembly isn't my language.) -ss
