HP Prime - Creating "Hello world" and transferring programs

[@v-creations24]

Which programming language is this

[@AntonioCavicchioni]

Thank you! Is it possible to store a number with an unit into a variable, as in the HP 50g?

[@LMGuzz]

Very helpful! Thank you very much!!

Hi! Do you know how I can have the Prime output a matrice (non-string but arithmetic result) on the screen in its normal form? After switching to the Prime from my old TI-89 I'm trying to write programs in this new Calculator and I started with a program which uses Cramers matrices method to apply the Kirhoff's laws on electric circuit exercises and since I want to use this program in the school in the exam tests I want it to show me the solving procedure step by step so I can write it on paper. However, I couldn't unfortunately manage to have it output ec. "J1= [3x3 matrice] / [3x3 matrice]" except of the command PRINT which printed the matrix on a screen named "Terminal" but only in a one-dimensional way, so it literally printed in one line "[[1,2,3],[4,5,6][7,8,9]]" (no string) which is not what I want! isn't it possible to print results like on a chalkboard on this calculator? it was even possible on my ultra-old TI-89! Hope you can help coz it's very hard to find understandable info either online or in the Prime's manual!

8 years later but engineering student here wondering if you were ever able to find a solution

Awesome, thank you so much!

Great tutorial! - Thank you :-)

all I get is syntax error

Terrible explainer. I'll go to a different video to find out how to ENTER a program.

Hello examples are most useless. At least you could have written a program that computes all prime numbers for a given range, or anything else that would take input from a user, use a loop and if statement. You could also have these primes plotted on a graph and draw best fit curve. You have very powerful calculator and you demonstrate it’s abilities with hello world.

How amusing... you clicked on a video whose title says "Creating 'Hello World'" to complain that it only shows you how to create a 'Hello World' program. What exactly did you think you were going to see? I've created videos with more complex topics that you are welcome to view. As for this particular one, the goal was to keep it extremely simple so that I could demonstrate other features, such as the connectivity kit and how to do transfers. I'm not sure why you particularly chose to watch a 'useless' video given that its title is clearly stated so that you could simply skip watching it. Never mind that it was created 7 years ago, back when little to nothing was known about this calculator -- including how to make a basic 'Hello Word' program. I suppose I should end with: complaining about 'Hello World' programs is useless when you can simply skip it after reading the title of the video.

@@rs1n you just don’t get it, do you?

@@vm2463 Not really (honest reply). I have uploaded a number of videos going over other types of programs for those wanting to get further into programming on the HP Prime. They range from simple Newton's method to 3D graphing to solving multiple non-linear systems. Your complaint about a video made many years ago (7 based on the date of the video, to be exact) to introduce the most basic of concepts on a calculator that was mostly undocumented (at the time) using a language (HPPPL) that was also fairly new has been noted. But I have no intentions of changing its content, nor plan to take it down, because users can simply choose to ignore the video itself if they find that their level of experience with the calculator is far beyond what this particular video provides. Based on the replies of other folks, it appears that some of them found it useful.

I think u are a really smart guy. Why dont u create a nice video about having the primes plotted ona graph and draw best fit curves. Maybe more productive than making a complain about watching a video that clearly says this is about a hello world program.
