If end of volume is recognized during processing of a READ statement and logical end of file has not been reached, the following actions are taken in the order listed:
  1. The standard ending volume label procedure is processed.
  2. A volume switch occurs.
  3. The standard beginning volume label procedure is run.
  4. The first data record of the next volume is made available.
