There may be some confusion over the term 'temporary dataset'. In the mainframe world, that does not mean just any old file that isn't needed long term. There are two types of data sets: temporary and non-temporary. z/OS does not define 'permanent' at all, only 'temporary'. Temporary data sets are assigned patterned names generated by the system. They cannot be cataloged. The only valid disposition is either PASS or DELETE, not KEEP. If the final disposition in a job is PASS, the system substitutes DELETE.
Finding a true temporary data set on a volume after the creating task has ended implies either a system crash or an APARable failure in the operating system. . .
