Hofer,
Don't forget to search help when looking for how to do something. You will get some helpful results if you search for comma delimited. Unfortunately, CSV is a complete miss (I'll file that as a bug). Once within help, there are often links that will take you directly to an example and/or to related examples.
For example, if you hover over Write to Spreadsheet File (either on a block diagram or a palette) and then click on the Context Help windows ? button or "click here for more help" link, it will open online help on that function. Near the top of the online help is a link to an example.
You can also use the Example Finder (via Help >> Find Examples) when specifically looking for examples.
Enjoy,
Roy
