Prime Programming help needed for a (still) newb Prime user
Hello all,
I have a programming question that is trivial on my HP50g, but not so much with the Prime. I often use my calculator as a simple "counter" for incrementing a number on the stack by a varying number, and I assign simple programs for these to softkeys. The simplest possible example (as I do it on the 50g) - "count by 1": << 1 + >> I store this as "CNT1", and press the softkey for it (after initially putting a zero on the stack), and I can increment the value on the stack with one button press. For the Prime, I came up with a simple prog: Code: // change the value in the RETURN statement for The above works, and assigns the countby() program to the unshifted comma key for the user keyboard. In practice this is rather clunky, though: - Put zero on stack - Press shift - Press Help (for user keyboard) - Press comma key (which puts countby() in the command line) - Press enter Is there a more elegant way to do this without requiring 4 keypresses? (Maybe within a custom app with an option to change the count increment?) Just fishing for ideas - I am sooo used to the RPL programming that this Prime is hard to get used to! |

The user guide has a brief explanation on the GETKEY function.
Apparently the code for the comma is 29. I have not coded an example yet. Thanks. |

Hello,
To use my HP prime as a simple counter, I never made something so elaborate. In HOME or CAS view, I press [ 0 ] [ ENTER ] to enter zero in the results stack. Then I press [ Shift ][ Ans ] [ + ] [ 1 ] [ENTER] to initiate increment by one. Then any further press on [ ENTER ] increase the “counter” one more unit. If you whish, you can program the "Ans+1"; sequence on a specific User key to spare a few keystrokes. |

That's a fact, I never use my HP Prime in RPN mode, I have much better hardware for this.
