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. This fuller name appears briefly in the display whenever you execute a
function — as long as you hold down the key, the name is displayed.
Example: Entering a Labeled Program.
The following keystrokes delete the previous program for the area of a circle and
enter a new one that includes a label and a return instruction. If you make a
mistake during entry, press
~
to delete the current program line, then reenter the
line correctly.
