ok, so this isn't really a bug, but it's a warning...if you run this code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14
| [0011223344556677]->pic1 7->D For(C,0,50) D+1->D If D=8 0->D End For(A,0,12) For(B,0,7) pt-on(A*8[+D],A*8+D,pic1 End End DispGraph End |
(note: [+D] is optional (take out the [] ))
you will with the extra +D on the completion of the program if you go to a menu and then back to homescreen your cursor will change to a insert-2nd one, and then your calc will crash and ram clear, if you exclude the extra +D then you will brick your calc...the same thing happens but instead of a insert-2nd cursor it is a lowercase-alpha cursor. and your calc will not crash but stay on that screen, and I tried pulling the batteries (all of the AAA's) out to no avail.
I was able to fix it though by linking a classmate's 84+ to mine and sending an empty L1 to my 83+, and upon the 84+ erroring because there was nothing receiving, my 83+ on the other-hand unfroze and I was able to do things with it, although the alpha cursor was stuck on lowercase... when I didn't try to clear the ram right away it froze again, and I had to send L1 again. the second time I immediately cleared my RAM and my calc is now fixed.
tl-dr;
don't display sprites off of the screen on the bottom, or to the right by 8 and then quit out of the program, bad things happen...
