Spanned records can span more than one block." https://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.idad400/da.htm Joe On Tue, Dec 22, 2020 at 8:37 AM Paul Gilmartin < [email protected]> wrote: > On Tue, 22 Dec 2020 13:37:58 +0000, Seymour J Metz wrote: > > >> 27998, the non-spanned maximum blocksize for 3390 devices, > > > >That's the optimal block size, not the maximum. > > > For QSAM and BSAM, thee maximum block size is 32760.
