Here’s the <a href=”http://www.as400tutorials.com/quick-as400-tutorial/”>5 minute tutorial</a>, and a <a href=”http://www.as400tutorials.info/”>good tutorial site</a>.
I’m favorably impressed by the tutorial site mentioned above. Bare simplicity is an excellent introduction. On the other hand, the huge volume of information from IBM covers (almost) every conceivable detail. It takes time to find the nuggets that can be useful in the beginning.
Here is an example IBM site with <a href=”http://www-03.ibm.com/servers/enable/site/education/ibo/view.html?all”>a collection of papers and some tutorials</a>. One example is the <a href=”http://www-03.ibm.com/servers/enable/site/education/abstracts/208e_abs.html”>CL programming exercise</a>.
<li><i>Note:</i> IBM has apparently made the ‘Collection’ page disappear. The individual internal pages are still accessible.</li>
On that exercise abstract page are links to other papers, tutorials and exercises.
Two good ones from there for beginners are <a href=”http://www-03.ibm.com/servers/enable/site/education/abstracts/techintro_abs.html”>Introduction to the IBM System i family</a> and the <a href=”http://www-03.ibm.com/servers/enable/site/education/abstracts/e822_abs.html”>IBM i5/OS text interface</a>. Most beginners need most of what’s in those as a foundation for everything else.
I suspect that any one of us who visits the links pages there will find something they want to review.
