Program Stops
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 R/S. The execution of a[Rr/s]instruction in a pro-
gram halts program execution at the step following the [r/s].
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 avoid 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-
quence 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[r/s]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.
19 61
20 14 03
21 01 Digit entry
22 03 Digit entry
23 04 Digit entry
24 73 Digit entry
25 07 Digit entry
26 15 22
To avoid problems like this, you should switch to PRGM mode
to see whether or not you are in the middle of a digit entry key
sequence. If you are, you should use Eggor B3l to correct the
situation. In this case, you should press ES@twice in PRGM
mode, then switch back to RUN mode and press [€3 . Finally
you can press [R/S]to resume program execution.
