Having a good accuracy (and support for R-/Z-) for Gamma would be of a great help, I should analyze the code and help find the optimisations.

Please take a look at the latest BASIC version. Conversion to HP-41C is left as an exercise to the reader :-) You can start with the extant RPN code, although it’s not properly optimized as it was just a test. Also, if you use Free42 remember the HP-41C has no recall arithmetic. The lack of that feature might make it difficult to do it all on the stack. Anyway it won’t hurt using a numbered register or two, most important it to keep the program as compact as possible.
