Instead of the equation input display as 1 and 2 changed to

Equation Input 1 to 1,111,111,111
Equation Input 2 to 2,222,222,222

Looks good. But the FIX commands are not required, and the 111.... can be reused to get the 222....:

Code:
01 STO 1 02 Rv 03 STO 2 04 Rv 05 STO 3 06  9 07 EEX 08  1 09  0 10 CHS 11 1/x 12 STO 0   // show 1111111111 13 STO+0   // and keep 2222222222 in R0 14 R/S 15 STO 4 16 Rv 17 STO 5 18 Rv 19 STO 6 20 RCL 0   // show 2222222222 21 R/S .. ...

Nine steps less. :-)

You can also do this with R7, but since here storage arithmetics are not possible you would have to replace the STO 0  STO+0 with STO 7 and the RCL 0 with RCL 7  2  x.
