Between the APIs by Example tips in this newsletter and various articles in iSeries NEWS, there are quite a few sample programs that show how to use iSeries APIs. I thought it would be helpful to list the many API sample programs and articles available online and organize the list using the API categories IBM uses in its InfoCenter documentation at http://publib.boulder.ibm.com/iseries/v5r2/ic2924/info/apis/aplist.htm.

I'll be including many more APIs by Example sample code in upcoming newsletter issues. If there are any APIs in particular that you'd like to see covered (or if you have API code you'd like to share), please contact me at mailto:clubtechprogrammingtips@iseriesnetwork.com.
