7/ PROGRAMMED CALCULATIONS
' This calculator has a program memory of 38 steps. Up to two programmed proce-
dures of calculation may be stored in the memory. '
'To store a program (mathematical procedure) in the calculator, execute ordinary
(i.e. manual) calculation in the LRN mode (press ) only once.
* Now the calculator has memorized the program. Input data and press the key.
and the calculator executes the program with the data. This is very convenient for
repeating calculations with varying sets of data.
