Program stops, displaying the
volume.
At
times a mistake
of
some kind
in
your
program will
stop
pro-
gram execution.
To
help you identify why
the
calculator
stopped
in
the
middle
of
your program, possible
reasons
are
listed below.
Executing
a RIS.
The
execution
of
a
~
instruction
in
a pro-
gram halts program execution at the step following the
~.
Executing
Step
00.
Whenever
step 00
is
executed
in a pro-
gram, program
execution
stops
at
step 00.
Pressing
Any
Key. Pressing any key halts program execution.
Be careful to a void pressing keys during program execution.
If
a
program has
been
stopped
by pressing a key, be careful not to
restart program execution in the middle
of
a digit entry key se-
q uence within the program.
For
example
in
the section
of
a pro-
gram shown below, if program
execution
halted at step
23
, the
number
13
would
appear
in
the display.
If~is
pressed
, the
number
13
would be automatically pushed up into the
stack
and
the number 4.7 would be keyed into the X-register.
