Hydraulics?I've been known to implement a linked list using a deck of cards, with tetrapod "one teaspoon of sugar" packets for the Next markers, and pens for externally-accessible references (the head of the list, the current node, etc). This therefore proves that a pointer IS a teaspoon of sugar, and vice versa. Would you like your tea with one pointer or two? ChrisA -- https://mail.python.org/mailman/listinfo/python-list
