[Coco] Basic09 Linked Lists

[Wayne Campbell]

Yes, there is a BYTE data type. However, used in the context indicated,
those values would probably be converted to integers anyway, and keeping
them as integers means you can have a larger list. Byte is limited to 256
(0-255) whereas integer allows 32768 (0-32767).
