Personal information
Heiko has been in IT since the 90s, but never worked with an AS/400...until 2019. He'll document his first steps in the hope they will be useful to others.

Project Hello World
Preparations
Things you need:
- an AS/400 (obviously :) )
- an working account
- log in
- command prompt
- maybe this for easy reference: Basic Commands
Creating a physical file to hold the sources
Every user has a personal library, like an home in an Linux environment. Since a user can have and use multiple libraries, the current (=default for all operations) is stored in *CURLIB[1]. Because the value of *CURLIB can be changed by the screen you are currently working in, all following commands will contain my personal library name HKRETSCHME. If you are sure *CURLIB is set correctly, you can omit the library.
This command creates a physical file named HELLO01:
CRTSRCPF FILE(HKRETSCHME/HELLO01) RCDLEN(112) TEXT('Project Hello World')
But I prefer to do this in more steps, which I'd recommend to every beginner (By the way: don't bother using cases, the AS/400 won't either. Using capital commands and names just makes it more readable in this article.):
CRTSRCPF
If you don't give any parameters for this command, you will be asked. [2]. This a very convenient way to use all the available options without looking them up:
Hint: Since giving no arguments won't work for all commands, try this: Enter the command you want to execute and then hit F4
