-This website contains several programs that I've written for this wonderful pocket-calculator: the HP-41C/CV/CX
-Some of these programs are very slow on a real HP-41, so it's sometimes better to use them
on a good emulator like V41 - written by Warren Furlow. See www.hp41.org
-You can convert the text files to raw files with http://www.hpmuseum.org/software/hp41uc.zip
-Another alternative is the new fantastic HP-41CL created by Monte Dalrymple. Cf www.systemyde.com/hp41/
-I hope that these routines will be useful ...
-If you want to learn the HP-41 programming language, I strongly recommend the 3 excellent books:
