Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of IBM Z Open Automation Utilities     *
  *                 (ZOAU) version 1.3.0.x                       *
  ****************************************************************
  * PROBLEM DESCRIPTION: In the ZOAU Python language pack,       *
  *                      the list_vsam_datasets() function       *
  *                      incorrectly throws an exception if no   *
  *                      datasets matching the provided pattern  *
  *                      are found. This PTF changes the         *
  *                      behavior so that an empty list is       *
  *                      returned.                               *
  ****************************************************************
