access to 9-track reel tape drive
Does anyone know of anyone in (or near) Central Florida (private individual or company) with a working mainframe compatible 9-track tape drive capable of reading tape reels recorded at 1600 or 6250 BPI density? I have a number of old tapes that need to be copied and archived, for "posterity." Please advise. Feel free to reply privately if you prefer. Thanks in advance. Mark S.

Re: EXTERNAL: Re: Why Would COPYSRVH Cause a 1M Page Demtion [Internal]
Here's what happened: Apar: OA41307 Abstract: FORK FAILURE WHEN ADDRESS SPACE OWNS 1MEG PAGES Closed Date: 13/02/23 RSM support for FORK copies high virtual memory objects from the parent address space to the child as part of duplicating the parent process' address space. However, the request currently fails if the parent process owns high virtual that consists of one megabyte pages. PROBLEM CONCLUSION: TEMPORARY FIX: * * HIPER * * COMMENTS: All pageable 1M pages in the parent address space will be demoted to 4k pages and copied into the child address space. The easiest and safest solution for the APAR was to simply demote the source 1MB pages so the the existing code could then handle them. Over the years, RSM has changed other functions to reduce the number of cases where demotion is done. For example, z/OS 2.2 avoids demotion when possible for PGSER FIX. and z/OS 2.3 tries to avoid demotion when IARV64 PAGEFIX fixes a portion of a 1MB page. Unfortunately, ForkCopy slipped through the cracks. As a result of your question, it is being added to the list of things to look at for a future release.

Not sure how you get "don't use templates" from what I wrote. Heck, I *over* used templates in the first large C++ project I ever did, and boy, does that make a mess! Now I think I am down to a happy medium. I don't see them as "competitive" (in a design sense) with macros. Overusing as in template meta-programming? https://en.wikipedia.org/wiki/Template_metaprogramming The XL C++ compiler is withering on the vine. The word is that IBM don't the resources to keep it up to date with the current standards so the xlclang++ port of clang using the existing Toby back-end is the way to go. If you use PDS data sets for your source your SOL as it's z/OS UNIX only and only produces 64-bit modules. But what I find exciting is that IBM have stated their intentions to fully port LLVM/clang/libc[++] to z/OS without a reliance on LE so supervisor state programming in C++ will be a reality without the nightmare of LE ESPIE/ESTAE condition handlers. https://lists.llvm.org/pipermail/llvm-dev/2020-June/142174.html Charles -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of David Crayford Sent: Tuesday, April 6, 2021 5:15 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Meta languages [was: RE: Assembler Language Programming for IBM System z Servers] On 6/04/2021 1:23 am, Charles Mills wrote: But IMHO none easy to learn or use. I am generally not a fan of meta languages at all. I think writing programs is hard enough, without having to write two effective programs: one that runs at compile time and one that runs at run time. In my C++, which is now my primary language, I eschew the use of C macros as much as reasonably possible. Reasonableness is a key here. For a few things, macros make sense. That's interesting. You don't use templates which are one the most powerful features of C++? Well, I didn't see a reference to LE in our statement of direction at https://community.ibm.com/community/user/ibmz-and-linuxone/blogs/robert-barrington1/2020/08/04/ibm-cc-and-fortran-compilers-to-adopt-llvm I believe the compiler will require LE for the foreseeable future, though if you want to request an LE free mode, I’m sure you can put in a request for it at the RFE site https://www.ibm.com/developerworks/rfe/ Hope this helps. Thanks for the clarification. I can see now that the work being commited is all libc++ but the C library is the system C library which in the case of z/OS is LE. It's also going to use the Itanium ABI so it won't be compatible with existing z/OS C++ code. IIRC, that's already the case with the latest release of xlclang++. It will be interesting to see what comes out of this when it's ready. Hopefully, anybody will be able to build languages supported by the LLVM framework such as Rust, Fortran, Ada etc. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN (apologies for late response . I missed seeing the follow on posts :-( Again, from our dev team: libc++ under the covers still uses the C runtime, which is still LE. As an aside, we are shipping libc++ under LE as well so even if there was no C dependency, there would still be an LE dependency.

Off Topic: Advanced Capacity Planning and Laundries
This is a long shot: Many years ago, probably early nineties, I attended a 1 week IBM course with the title “MVS Advanced Capacity Planning” (or similar). It was given by a Canadian IBMer. At the start of the course he gave out, without further explanation, copies of some articles. One was a story about a student who used a Chinese laundry. The proprietor used the laundry items to make deductions about the student’s life, eventually concluding that the student had committed a murder. (All wrong of course - hence the link to capacity planning). I think the story was from one of the Stephen Potter books (who wrote about “Gamesmanship etc in the 1950’s). Does anyone else remember this and have details of the source ?
