Program Memory
As you may remember from the heat loss program you keyed in at
the beginning of this handbook, the keystrokes used to calculate a
solution manually are also used when you write a program to
calculate the solution automatically. These keystrokes are stored in
the calculator's program memory. Press (-]000 now to return
the calculator to the top of program memory. If you have not
already done so, set the calculator to Program mode by pressing (9]
[P/R]. (Remember, whenever the calculator is in Program mode, the
PRGM annunciator will be visible in the display.) The display
should now show 000-, which is the top of (program) memory
marker.
