Thanks for the program! The algorithm will be perfect for calculators that don't have native complex numbers. Thanks also for your prompt fixing of the typos. All examples work fine now:
Have you considered using Jean-François Garnier's
Emu71 emulator? You can avoid typing errors by editing your program on the emulator and copying the program lines from the DOS windows and pasting them to your text editor (I think this should be possible also on Christoph Giesselink's HP71B Emulator).
Since there is no line between lines 68 and 70, you can save a few bytes by rewriting line 68 as
68 IF K<0 THEN 90
