RTFM ? Message #4 Posted by thibaut.be on 22 Feb 2002, 8:25 a.m., in response to message #2 by John Ioannidis Well, even if present manuals are the last thing to refer to when a problem arises, I need to say that the prior 1986 HP manuals arere examples of their kind many manufacturers should refer to. There were a lot of examples and labs, and allways with the same touch of humor that I appreciate a lot. Everybody remembers lovesick sailor who by chance had a 41C in his bag, don't you ? BTW, the R^function could also be accessed y... 3 times RDN :-)

Re: What key for "R^" in a program HP-41CV Message #8 Posted by Tony Duell (UK) on 21 Feb 2002, 2:04 p.m., in response to message #1 by Michel The HP41 has many more functions than keys, so there's not always a key to press to enter a function. What you do in that case is press <XEQ> then <alpha>, then type in the name of the function, then press <alpha> again. This works both in 'run' mode (to execute a function not on the keyboard) and in program mode (to enter the function a a program line). So in your case, press <XEQ> <alpha> R ^ <alpha> (where ^ is typed as <shift> <enter> -- there's a label on the back giving the shifted alpha characters). Oh yes <xxx> means press the key with 'xxx' on it. I would recomend trying to get the user manual, though. It's got a lot of good information in it. Another good book is 'Extend your HP41' by Wlodek Mier-J. That's probably the most useful 3rd party book for general users -- it covers everything from turning the machine on to synthetic programming. I use my copy all the time.

This can save a lot of typing of those alpha function names.

Re: What key for "R^" in a program HP-41CV Message #10 Posted by Todd G. on 22 Feb 2002, 5:15 a.m., in response to message #9 by David Smith All the standard functions are listed in one of the "Catalogs" that is available for viewing by pressing "f" ENTER, I think. Whenever I cannot remember the abbreviation for a function, I refer to the catalog first. Todd
