Sounds like the answer is yes: 'SC23-6852-03 z-OS DFSMS Macro Instructions for Data Sets V2R2 2015 dgt3d510.pdf' BSAM READ Macro Addressing mode: When you issue the READ macro in 24-bit mode, provide only 24-bit addresses unless you code SF64 or SF64P. When you issue the READ macro in 31-bit addressing mode, provide only 31-bit addresses unless documentation says otherwise or you code SF64 or SF64P. With SF64 or SF64P, the data area can reside above the 2 GB bar but you cannot issue READ in 64-bit mode. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
