Chapter 13: Programming Features Example The following data are included in list L1. L1: 165, 182.5, 173.8, 166.5, 185.3 A one-variable calculation was executed based on this data. After returning to the calculation screen, average values can be viewed by using the following procedure. • Press @ z H E A _ 0 2 to display "x" on the screen. • Press E to obtain the average value of X as determined in the previous calculation. • In this way, the contents of an immediately preceding statistical calculation can be stored as statistical values. • These contents remain valid until the next statistical calculation is executed, even if the power is turned off. • The same is true even for regression calculations and verification calculations. 8. Debugging After programming, it is required to debug the program. 1. Press P A and select the program to debug. If any bugs are present, error messages will appear. The following example indicates that the same label name has been used two or more times. 2. Press ; or ' to display the line where the error exists and correct the mistake. 219

Chapter 13: Programming Features
Example
The following data are included in list L1.
L1: 165, 182.5, 173.8, 166.5, 185.3
A one-variable calculation was executed based on this data.
After returning to the calculation screen, average values can be
viewed by using the following procedure.
• Press
@
z
H
E
A
0
2
to
display “x
_
” on the screen.
• Press
E
to obtain the
average value of X as
determined in the previous calculation.
In this way, the contents of an immediately preceding statistical
calculation can be stored as statistical values.
These contents remain valid until the next statistical calculation
is executed, even if the power is turned off.
The same is true even for regression calculations and verifica-
tion calculations.
8. Debugging
After programming, it is required to debug the program.
1. Press
P
A
and select the program to debug.
If any bugs are present, error messages will appear.
The following example indicates that the same label name has
been used two or more times.
2. Press
;
or
'
to display the line where the error exists
and correct the mistake.
