Wow, my first posting in c.s.handhelds. I've been reading since July. 
I just had to get one in tell my kids that I posted to handhelds
about the 48 BEFORE we got our own group. I got my E on Oct. 11th
so I even got Minehunt! Yeah!

Anyway, I remember seeing stuff about the tetris pause function
preventing the auto-shutoff but I didn't see a fix. My fix simply
does away with the infinite loop in INFLP. It also catches one ATTN.
Replace INFLP with with the following.
<< IFERR 0 WAIT THEN END DROP >>

Since WAIT leaves the calc idle until a key is pressed, the auto-shutoff
still works. The IFERR allows a clean continuation after pressing ON to
restart. This also fixes the same problem in the high score screen, BTW.

Another place I found useful for IFERR was in 'start'.
Replace TETRIS in 'start' by IFERR TETRIS THEN END
I kept hitting ON instead of Q to exit so I always had to carefully
objects until I got to the saved flags and typed STOF. Really annoying.

The only other "fix" I found useful other than key changes was modifying
RK2 so that the OFF became << OFF INFLP >>. This pauses the game if you
shut off your calc with the O command in tetris.

These were all such tiny fixes that they can typed in by hand and
(hopefully) added to the next release.
