IBM still supports the KEYLEN parameter in the DCB macro for new user-created data sets in BSAM, BDAM, and BPAM. The VTOC and PDS directory are the only system structures still using keys, but access methods are also part of the operating system and are supported. IBM still supports having their customers create keyed files. As long as customers continue creating and using keyed files, IBM must continue supporting them in the z/OS access methods.

(was: Physical record size query) Yes, I listed only two things supported, but you did not add anything else which is SUPPORTED. ISAM datasets, PASSWORD - those things are dead now. User applications? Well, there still can be user applications using ISAM... but usage of ISAM is *impossible* on current systems. Existing ISAM files can be deleted - the only support for ISAM. AFAIK The application can still work with VSAM files, using IIP. Of course that means no KEY of CKD.
