When you store a list, lets say to l and type in l(a), where a is an element,
it has an error.. why does it work?
on the 86 if you type in
{1,2,3} ---> l
l(2)
and then it displays 2, since 2 is the second element of that list
on the 89 if you type in
{1,2,3} ---> l
l(2)
it displays "Error: Not a function" or something like that.... How
do you display an element of a list on the 89?
Thanks,
