I did not claim that. (Did you want to reply to a different post than mine?) >RECFM=V on z/OS has BOTH the BDW and the RDW. Just what I said, and the BDW is 4 bytes. -- Peter Hunkeler -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Peter Hunkeler Sent: Friday, December 16, 2016 9:00 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: AW: Re: 32767? >The BLKSIZE must be 4 more than LRECL for a RECFM=V dataset and 8 for a RECFM=VB dataset. When it comes to BLKSIZE versus LRECL, there is *no* difference between RECFM=V and RECFM=VB. And even the print control character variants with the additional A or M in th RECFM do not make it any different. A block is a block and a such it has a 4 byte BDW (for RECFM=V.... only, of course). To "B" or not only tells the reader or writer code whether exactly one or possibly multiple logical records are in the block. It doesn't change the format of the block. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
