Calling a program on the i via OpenSSH

I have no clue what I am really talking about here so please bear with me.
My end goal for this request is for a Windows server to connect to an IBM I
and issue the command and receive the results without any user intervention
via a "windows script".



I already have OpenSSH running on the i and I can log in with PuTTY.



Now my request.



Can anyone provide a sample program (or point me to one), preferably written
in RPGLE that can be run on the iSeries from a Windows 10 PuTTY session and
have it return data back to the PuTTY session? I would be OK if it just
returned "Hello World". In the real world, I will need to generate data and
return it to the caller but Hello World would get me started.



Just in case my request is not clear (because I don't know 100% what I am
asking for), here are the steps I think I need.

1. Start PuTTY on a Windows 10 machine
2. Connect to my IBM i
3. CALL HELLOWORLD on the IBM I <-- if you can provide the correct
syntax too, that would be great
4. See "Hello World" in my PuTTY window.
