This won't work if X = 0.

See: ->P and ->R conversions for the HP-35s in the Original Software Library.

Yes, thank you! Well and good, and my bad too on another thing... I noticed that the routine really needs to decompose the complex (which mine does not yet) ... maybe later tonight.

Paul, how do you want LASTx to work with this type of routine; which LASTx should be left in the LASTx register. i know the definition of "value of x just before the last operation" but that definition really depends on the *operations* defined for LASTx. I can think of several ways to make sense of LASTx with a complex decomposition routine. Just wondering what your take was. Thanks.
