=== Creating a physical file to hold the sources ===
== See also ==
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 <tt>*CURLIB</tt><ref>https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_71/rzarl/rzarlcurlib.htm</ref>.
* [[Basic Commands]]
Because the value of <tt>*CURLIB</tt> can be changed by the screen you are currently working in, all following commands will contain my personal library name <tt>HKRETSCHME</tt>. If you are sure <tt>*CURLIB</tt> is set correctly, you can omit the library.


This command creates a physical file named <tt>HELLO01</tt>:
== Footnotes ==
 
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. This works great for <tt>CRTSRCPF</tt>, but in general, OS/400 will only ask for '''necessary''' arguments. Some commands, like <tt>CHGUSRPRF</tt> will just do nothing.
This always works:<br/>'''''Enter the command you want to execute and then hit <tt>F4</tt>'''''.

==== A small detour: Physical Files? ====
[[User:Heiko|Heiko]] struggled a lot with this and thinks a small introduction is necessary:
* Libraries: Every user has his own personal library, think of it like a Linux home directory. TBD: wann kommen Libs noch ins Spiel? Per app? Per Screen? Per was? {WIP}
* Phsyical Files: Of course this is no phsysical file, you can't touch it. And don't think of if (like I as a german<ref>Yes, as a german IT guy you think of "file" as "Datei". But "file" in english can also mean "Akte" or "Karton mit Akten". Sorry for Kauderwelsch.</ref> do) as one file (f.e. <tt>/etc/passwd</tt>), it's more like an collection of informations, like you might know from MacOS resources.
* Member: A member is a file in an phsysical file, like a book in a filing box.
 
A more visal approach of explaining:<br/>
[[Image:PhysicalFileOrWhat.png|400px]]
 
The <tt>Library</tt> is the room you keep your <tt>Physical Files</tt> (think of filing boxes) in. The <tt>Physical Files</tt> contain <tt>Members</tt> (think of them like books).

About

This is Heikos personal page, in which he maybe shares some private information or collects bits for new articles.

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.

Too many F-Keys to memorize

I'm using a small apple keyboard on which the F-keys aren't labeled very well. This helps a lot:
