Re: Finding a member in a DD concatenation

If I understand the question, I think that the BPAM access method already does what you are asking for. If you concatenate partitioned datasets and then OPEN, BLDL, FIND, POINT, READ... then you can read the member found first in the concatenation. See "DFSMS Using Data Sets" / "Processing a PDS

Finding a member in a DD concatenation

I'm pretty sure the answer to this is no (at least not easily), but can't hurt to ask. The following, of course, works: //PARMS DD DISP=SHR,DSN=PROD.APPLIB.PARMS(ABC) Is there some way I could specify a DD concatenation where the system would search the DD's in order until it found a named
