The manual PARJDEV will provide you enough information to give you a head start.

As DSG points out you can easily read the difference between datasets and flat files in the manual. With the copy stage I often use it as a "placeholder" stage which simply transfers input columns to output columns in straight mapping. This stage will disappear when the job is run. It lets me replace it with another stage later on. It can also be used to remove columns, or copy the data down multiple output links.

Dump can be taken directly from dataset too.
