UPDTE - CBTTAPE 093

I've been using this program for quite a few years, found a problem that's been corrected, but today I seem to have found another issue, and I hope someone can tell me if its a bug or something else. I'm trying to load a file uploaded from Windows to a PDS (RECFM=VB,LRECL=259) and this works

Sorry, typo; should be "I believe that with REFRPROT, a 5KiB module with REFR will be loaded into two pages both of which are page protected.". There are large pages, but they are not the norm and come with some restrictions. -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3

Re: authority needed to update system symbols

If you're protecting OPERCMDS you need UPDATE access to MVS.SETLOAD.IEASYM. AFAIK there's nothing more specific to protect individual symbols. Mark Jacobs Sent from ProtonMail, Swiss-based encrypted email. GPG Public Key - https://api.protonmail.ch/pks/lookup?op=get=markjac...@protonmail.com

thank you for the information! in order to change a system symbolic I would execute a "setload" command? if so that would involve replacing the whole parmlib member and also authority to edit the parmlib dataset? Bill -- For

Re: authority needed to update system symbols

Take a look at IEASYMU2 as well: https://www.ibm.com/docs/en/zos/2.4.0?topic=definitions-changing-system-symbols I kind of like this option over SETLOAD if the contents/concatenation of IEASYMxx member is supported by more than one team. On Mon, Aug 30, 2021 at 6:45 AM Bill Giannelli wrote: >

FWIW and FYI.   A 31-bit instrucion is a 4-byte fullword address, as e.g. say at virtual (DAT) address x'71234568'.   The first 3 nybles (x'712') indicate the segment from which the LMOD's storage/address has been allocated. The next 2 nybles (x'34') are the offset to the page within the segment

The undocumented TRAP name in DIAGxx was something I added at very low cost for my use. For documented things, we have a more extensive (and thus costly) process, including: - Design documents - Design document reviews - Formal testing - Interface Change Notification to software vendors

New York responds, courteously. On a test system, you may specify the undocumented CsvSP252RoundUpTRAPS name in DIAGxx. For a module being loaded into subpool 252, that will round the length up to a 4K multiple. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp.
