Re: Accessing Functions on HP41 Message #2 Posted by Eric Smith on 30 June 2005, 8:41 p.m., in response to message #1 by Mike T.
Use the key sequence XEQ ALPHA F R C ALPHA.
You can find the function names of built-in functions using CATALOG 3.
If you use a function frequently, you may want to assign it to a key. For instance, if you're not using TAN, you could give the sequence shift ASN ALPHA F R C ALPHA TAN. Now if you put the calculator in user mode, the TAN key will instead act as FRC.
You can see what function a key is assigned by pressing and holding the key. The function name will be shown in the display. If you release the key, it will execute. But if you hold the key for more than a second or so, it will change to NULL, and then when you release it nothing will happen. That way if you're not sure about using a key, you can find out what it is.
