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>.
* [[:Category:Programming]]
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>. It could be omitted if you're sure, <tt>*CURLIB</tt> is set correctly.

* [[Editing Source Files using Eclipse and FTP]]
* [[Compile Sources Without Queuing]]
* [[How to solve Variadic Arguments issue (using C)]]

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

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):

If you don't give any parameters, you will be asked. This a very convenient way use all the available options without looking them up:

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.

Ideas for new articles

tbd

Articles to maintain

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:
