I would be remiss if I didn't point out that CMS has a VSAM API redirector in it. Look at the SUBSYS operand of FILEDEF. We added it in 1984 or thereabouts and the SQL/DS product had hook to let it process VSAM requests. I don't know if DB2 for VM/VSE still supports that. Look at "Interface to an Alternate VSAM Emulator" in the CMS Application Development Guide for Assembler. Your routine gets control on OPEN, CLOSE, and CLOSE TYPE=T with the address of the ACB. On OPEN your routine fills in the read/write vectors in the ACB. Alan Altmark z/VM Development IBM Endicott
