Have you compared it to my program in (15C) Halley's Method?
Don't forget to remove the PSE-command in line 058.

It would be interesting to see your program.
I will try your program.
I wrote mine on the go15c precise emulator for Android. It does not allow to export memory, so it is difficult to type it again here. But basically I did the following:
-Start with Valentin's 35S program;
-Replace lettered registers with numbered ones (e.g X became 4 for the real part and .4 for the imaginary part)
-Everywhere you have a STO, replace it with something like: STO 6, Re<>Im, STO .6, Re<>Im
-Everywhere you have a RCL, replace it with: RCL .6, Re<>Im, CLX, RCL 6
-Replace the equations at the beginning with RPN code.
-Ignore recall arithmetics altogher: RCL* becomes RCL, then *
-Ignore the cosmetic ending about considering the a root is real if its imaginary part is very small. Pointless with the 15C display capabilities.

Of course this is not optimized compared to a native 15C program!

Cheers
