Fine, thank you.

I have learn that putting ..... 1 R/S and .....2 R/S to separate equation #1 and #2 then show Determinant with the next R/S so that not to confuse user.

All this looks even nicer if the display shows 1,111111–11 and 2,222222–22. This shows more clearly that this is a marker and not an entered number. You can see how this looks like if you store these two numbers in R7 and R8 and replace the "1" and "2" with RCL 7 and RCL 8. ;-)

BTW, if you replace the final "GTO 00" in my version with "GTO 23" pressing R/S continuously displays X, Y, X, Y, X, Y...
