APAR status

• Closed as program error.

Error description

• IBM Explorer 3.0.0 browse function does not set an ENQ for SEQ
  data set
  
  To reproduce, open a data set in browse mode. (RSE View -
  contextmenu - browse)
  
  In the properties observe that the lock owner is empty and in
  ISPF there is no ENQ.
  
  With the editor still open in ISPF delete the data set. Observe
  that delete succeeds
  
  Observe the same behaviour exists when browsing the data set in
  the RDz editor in browse mode from within a plugin.
  
  The data set should be marked as in use (ENQ) while it is open
  for browse.
