When creating the definition of a multi-statement function, it may be helpful to visualize it
first in a block form.
Ê
Func and EndFunc must begin and end the function.
Ë
Variables not in the argument list must be declared as local.
Ì
Returns a message if nn is not an integer or if nn
{
0.
Í
Sums the reciprocals.
Î
Returns the sum.
When entering a multi-statement function on the calculator Home screen, you must enter
