Program "Ephemeris" for HP CV 41


Please HELP! I am trying to input into my Hp Cv 41 the program typed that I found in the "Museum of HP Calculators". I find this line: X<>Z. But my computer answers: "Non Existent". Why? does it lack of something? Without this instruction I can't proceed. Thanks in advance!


Hello Catello,

to enter X<>Z do the following:

shift I
shift J

shift is the yellow key. After the second press on "Alpha" the display should read: X<>_ _. After pressing the dot the display should read X<> ST_. Now only "Z" needs to be pressed.

Hope this helps.




Thank you sooooo much!!!! It works!!! Thank you again
