Break Infinite Loop - Nspire CX

[jonjoel]

Hi all,

What's the easiest way to break out of an infinite loop on the CX?  I usually just remove a battery on the older handhelds.  What's the equivalent on the CX?

Thanks,

Jon

Hold down ON for about 10 seconds and see if that helps.

This should interrupt calculations that you don't want to wait for.

This method doesn't interrupt dialog boxes or request commands.
Infinite loops may take a little while to respond to holding down ON.

Is there an equivalent in the 'student software'?  

I seem to have to kill the process if I create a tight infinite loop, even if it does IO.

[Suhail Sallam]

The student software runs on the computer, use Task Manager to kill the process.

I give credit to our old friend Nelson from Portugal who about this day four years ago wrote,

"After some browsing through the user manual I found the way to do it: press and hold the Pause/Break key for a few seconds (it took about 6 or 7 seconds to work in my case) and the program execution is interrupted!"

[Dennis Donovan]

This was posted to this group at some point:

- To stop a function or program (useful when in an infinite loop) on Windows, hold F12 and press Enter repeatedly. On Mac, hold F5 and press Enter repeatedly. On HH, hold HOME and press Enter repeatedly.  Or on HH hold ESC for more than 5 seconds.

I can verify that it works on the Teacher Software in Windows.  I have a screen capture program that uses the Pause/Break key, so I'm not sure how that would affect the functionality of that method.

I am not at all sure that pressing enter is necessary.

My recall was to hold down for a few seconds: F5 for Mac, and ESC for handheld. Not being a native Windows user, I can't vouch for F12 but it sounds reasonable.

I suspect pressing enter repeatedly just helps to pass the time...

With best wishes,
Steve

In the SS manual it definitely says "Hold down the F5 key and press Enter repeatedly" for the Mac.  F12 on Windows, but the same note about pressing Enter repeatedly!

Anyway, this doesn't work for me.

There I was, trying to pass the time by pressing [enter] while holding down the F12 key (on my Windows 10 computer).

Eventually I gave up, having insufficient time to continue passing it, so I forced a quit with Task Manager. Lost all unsaved work, but, such is life.

Has anyone found a more foolproof way to break out of an infinite loop?

Don’t ‘hold down’ the F12 key… Alternate F12 – Enter – F12 – Enter – F12 – Enter – Yada, yada, yada…
