[Tutor] creating a list of data . . .

[Kirk Bailey]

KIRK! KIRK! KIRK! (counting the cadence by pounding on crt with a large fuzzy 
stuffed monkey from the bookshelf to the right...) :-)

Scottish, not German!
(Dad's band of vikings went north, not east.)

But read on, this is more than a egotistical rant.

whups, this escaped me earlier. you can only access PART of it? data is acessed 
numerically, just like a list, address starting with 0 of course.  If you can't 
access all of it at will, something is TERRIBLY WRONG.

Right. You want some form of data construct that contains each datum in it's own 
'cell', and you simply access that cell.

KIRK! And rebinding is a pain.

Also reccomended in some tutorials.

Veryfine, and much preferred to messing with tuples. Turn it into a list, play 
with the list, then turn it into a tuple- which is meaning what I said, but at 
much greater detail and length: Destroy it and recreate it.
