Ok, I looked it up. "You can use partitioned concatenation only when the DCB is open for input." https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.2.0/com.ibm.zos.v2r2.idad400/d4329.htm It makes sense. What would it mean to open it for output? Which PDS would be selected to write a new member to? What if you are writing to a member that already exists in one or more of the PDSes? What if the PDS that already contains a member by the same name doesn't have room for the member? -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
