Subject: RE:
I'll make a couple of observations. You have a single extent statement for the file so you are using automatic secondary allocation support instead of using the Dynam catalog. You have 4 actual output extents that are all on the same volume. You have a BLKSIZE specified on the DLBL for the input step but not on the output step. I'm not sure that makes a difference but it looks a bit strange.
The sequence is the program reads extent sequence numbers 0-3 over and over. When using automatic secondary allocation, Dynam/D uses only 2 label records, the current extent sequence number and the next sequence number. The labels are updated at each end of extent to match the currently active extent sequence numbers.
Given the above, it seems to me the program must be closing the file and opening it again in order to get the sequence number reset to 0. However, my experience with the operation of D/D is very old and things could have changed somewhat over the last 24 years. If you don't see the program doing the close/open, I would run a Dyanm/D DIAG trace or SDAIDS fetch/load trace to see if CLOSE ($$BCLOSE) is being called followed by OPEN. If all you see being called is EOV, when the extent sequence number changes from 3 to 0 then you should call CA. Otherwise, correct the program to not Close/Open the file.
