anybody familiar with TI Nspire app for iPad?

I've been able to figure out how to create Functions, store and use them, but Programs, there's a different matter...

My trouble is if I create a program that accepts/requires no arguments, the program fails to run with "Error: Argument error"

If I put in a dummy argument, it will run, any ideas? I tried using (void) but that doesn't work, it will only accept a variable such as a,b,c etc... I had a similar problem when I tried to create and use a Function until I learned how to "Check Syntax and Store"; that fixed the Argument error for the functions but this Program error is something different.

Documentation is really sketchy for this app and there are precious few examples on the Internet for it but it seems to hold promise. There are lots of articles and YouTube videos for the Nspire CX CAS calculator, but from trying to follow along, I have found that only bits and pieces of those apply.

To create a program that requires no arguments make sure not to put a variable in the parentheses next to the program name in the program editor. When running your program, you would then enter your program name followed by an empty set of parentheses. An example of making a program that requires no arguments can be found at the URL below:

Geez, that was simple! That example that you sent was the exact same one that I followed, I did everything correct EXCEPT call it with hello() I kept trying with just hello but now that you point it out, it was right there in front of me the whole time.

btw, is there a way to set the keyboard default to the TI keyboard instead of the iPad keyboard, it's kind of a pain to switch keyboards so often, for instance, if I have a program that is asking for input, say six variables, I must switch the keyboard 6 times to use the TI keyboard. Of course I could just use the iPad keyboard, but, to enter a number, which is most often what I am entering, I have to press the .?123 key to switch to the numbers so the TI keypad is much better for me...

Thanks so much!
