Function Names in Programs
The name of a function that is used in a program line is not necessarily the same as
the function's name on its key, in its menu, or in an equation. The name that is used
in a program is usually a fuller abbreviation than that which can fit on a key or in a
menu.
Example: Entering a Labeled Program.
The following keystrokes delete the previous program for the area of a circle and
