I don't know why I can't write HMS--> function under some bigger function that contains HMS--> , in Algebraic expression when my expression is writen under quoted marks ( ' ' ). Of course I everything do in RPN calculator mode . Here is example : underneath pictures
So how Can i write this expression under quoted marks , that will bring me a good result
Then when I hit ENTER button it show's me something like thatFirst i enter all my numbers under ' 'That is continued part of entering...
That's because HMS→ is a command, not a function. It cannot be included inside algebraic objects in RPN mode.
However, there's a nice trick that lets you use any command (e.g. HMS→) as if it were a function, and that's by wrapping it in a "user-defined function". For example, type the following on your 50g in RPN mode:
« → t « t HMS→ » »
This creates a user-defined function called HR which acts just like HR on the HP-41, and just like HMS→ on the 50g, but it's allowed inside algebraic expressions on the 50g. So '1+HR(2.3)' is allowed. Cool, huh?
