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] will just do nothing.</ref>. 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.

  2. In general, OS/400 will ask for necessary arguments. Some commands, like CHGUSRPRF
