Bob quoted the JCL manual. So yes, DUMMY is usable with QSAM. The issue however is what is IEBCOPY's requirement. My manual says SYSUT2 must reside on a device that supports QSAM, such as (but not limited to) DASD or tape. Since a DUMMY dataset does not reside on a device, it fails that test.
The fact that the error message refers only to DASD and tape is just another example of poor wording. Why IEBCOPY has such an apparently unneeded restriction is a different question. And the original issue about member lists is solved by using VIO instead of DUMMY. :>: -----Original Message----- :>: From: IBM Mainframe Assembler List [mailto:ASSEMBLER- :>: [email protected]] On Behalf Of John Gilmore :>: Sent: Saturday, June 07, 2014 9:07 AM :>: To: [email protected] :>: Subject: Re: ADRDSSU VTOC -- also IEBCOPY :>: :>: Bob Raicer can defend his own positions, but it does seem to me that :>: he made it clear, with appropriate extracts from the manual, that :>: DUMMY is usable only with BSAM, QSAM, and VSAM, i.e., not with BPAM. :>: :>: That being the case, most of this backing and filling is, at best, :>: irrelevant. :>: :>: John Gilmore, Ashland, MA 01721 - USA
