Hi Mark, In respect of your VSAM close giving RC=4. I am not a VSAM expert so the following may be off beam, but I remembered this quote from the Data Set Macros Manual.
"Requirement: If you are sharing subtasks or if you have issued an asynchronous request for access to a data set, you must issue a CHECK or an ENDREQ on all RPLs before you issue a CLOSE or CLOSE TYPE=T. Otherwise, concurrent data set I/O activity causes unpredictable results during a close." I wondered if the above fits with your question? "Is there any IO call that would/could/should leave the ACBBUSY flag set when it returns? It would seem that this is the most obvious difference between all the ACBs."
