(Full version, previous was sent prematurely) It is not strange, but fully explainable since several different processes work on 1 dataset: 1. IDCAMS writes sequentially to the dataset and has no problem writing to it. 2. The dataset's tracks are used for 98% 3. The dataset cannot be read as a PDS, which is quite understandable after step 1. The 2 processes that should never have interacted on the same dataset are 1. (write seq) and 3. (read PO) and that is the user's fault. It would have been nice if z/OS had avoided this, but unfortunately it doesnot as R.S. pointed out and most of us experienced once in their learning period.
