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,
