So now I'm confused. Are you saying that you typed it in as written, and that you still got the incorrect results? Or did you mean to say that you originally typed in "PushT/FLoop"?

If you meant the latter, then the typo correction should fix things. If you meant the former, then I'm not sure why your calculator would respond incorrectly to this code. It implies that the O/S is reporting an error code in response to the ACCESSSD command instead of the expected result, which could mean that there's a problem with the contents of the card. If you have another card to try, see if you encounter the same results when using the alternate card.

Sorry for confusing you. I change PushF/TLoop into PushT/FLoop and program now working well.

PushF/TLoop and PushT/FLoop seemed to be easy to confuse, so I said so (It made me confused).
