Re: 15C flashing display Message #2 Posted by Valentin Albillo on 13 Nov 2006, 6:21 p.m., in response to message #1 by Hal Bitton
There are two documented ways to make the display blink as you mention:
- An overflow condition, where the result of some computation exceeds the available range (i.e., > 9.999999999E+99). A running program which generates an overflow will continue running, but when it eventually stops, the display will be left blinking (unless the program clears flag 9, as discussed next).
- Manually setting flag 9
You can stop the display blinking by pressing the backarrow key, executing CF 9, or turning off the machine. If it turns itself off, flag 9 won't be cleared.
Best regards from V.
