LMAO!
Yeah, that sounds about right...
At my school, the staff didn't really "understand" new-fangled things
like electrisity, etc. After many years, we eventually got a few 186
PCs. Within about 4 weeks somebody had figured out that the teacher's
password was "teacher", and had installed the (then very new) Doom on
the PC. (Inside a folder called ".", IIRC. This made running the program
rather difficult! But that was the idea... tho personally I don't think
they need have bothered.)
Seriously though - I currently have a graphing calculator which is
"programmable". That is, you can make the menus appear in a pre-scripted
order, and fill in some of the fields with hard-coded values. Or even
the contents of variables (of which there are 26 available). What you
*can't* do is conditional branching, looping, subroutines, user input...
The calculator has a feature to graph a table, and to tabulate a
function, and to tabulate a recursive function. But if the recursion
isn't one of the 3 formats the calculator supports... you *cannot*
compute it automatically. You must do it by hand. Oh, and you can't
build a table by hand. In short, without using lots of paper, it is
*impossible* to graph anything except an explicit function or a few
specific kinds of recursion. Very programmable...
I'm hoping that a TI-81 wouldn't have such limitations.
