Re: A question about Xephon publicatiion(s)
Hi, Mike, The official repository of all the Xephon articles (that we have copies of) are here: ? ? See here for an explanation of the status of those articles and permitted uses: ? ?? ? If you have any specific questions about this, contact Sam Golub at? sbgolub@...? ... Also, if you happen to have any issues of Xephon magazines that are "missing" from the on-line collection at CBTTape.org, let me know, and I can get them converted to PDF and sent to Sam to update the web site.

A question about Xephon publicatiion(s)
Hi!
I noticed post containing old Xephon publications containing VMUpdate old articles from 1987-1995.? One can find pdf copies of VMUpdate since 1997. What is the copyright now? Are we allowed to post those old articles?

Re: Anyone have a VM Assembly language and/or Rexx
Hi, Bertram,
(private reply to you only...)
I am not exactly sure what you may be looking for??
What kinds of features comprises a "VM Assembler Toolkit"?
For example, one popular option added "structured programming" macros to 360/370 BAL/ALC -- see:?
? ? ?
for a detailed description of IBM's original CONCEPT*14 macros by Marvin Kessler.? CONCEPT*14 macros were used by many shops; a modified version is included in the modern IBM HLASM Toolkit.? There are links on the above page to a webified version of Marvin Kessler's original paper describing CONCEPT*14 ...
? ?
and "Appendix III" contains "coding instructions" for using CONCEPT*14:
? ?
See also the Waterloo tapes directory in the "Files" area of this H390-VM group list, and look at the tape for Release 5 of VM/CMS ... (Waterloo5.7z) ...? you can restore the "directory" with "TAPE LOAD * * A" from the first file on those tapes ... this will restore "ABSTRACT ABSTRACT" that describes all of the files on that tape, and the PETAPE MODULE that you need to use to LOAD any of the remaining files on those tapes.? (PETAPE was a modified CMS TAPE command, written by Perkin-Elmer Corp. back in the day, and contributed to the SHARE VM Project and is included on file 1 of each of those Waterloo tapes.)? ?
In the ABSTRACT ABSTRACT file for the Waterloo Release 5 tape, look for M1112V00 -- file 113 on the tape ... The PROC System.? This might be a good start for a "tool-kit" similar to you are looking for.??
The PROC System also supports a lightweight multitasking capability, similar to modern "threads" ... :-)
Note that several other files on that Release 5 tape use "The PROC System" macros (and runtime routines), such as file M1113V00 (file 114 on the tape) -- "SEDIT" an XEDIT-like editor (developed years before XEDIT), but without 3270 full screen support -- it was used mainly on "glass teletypes" ... dial-up line-at-a-time VM/CMS terminals.?
I hope that helps ...?

Anyone have a VM Assembly language and/or Rexx
Hello,
When I was in college I started an IBM 370 VM Assembly language toolkit. Over?the years I upgraded it to include XA, 390, and ESA, as well as Rexx.
Unfortunately I wasn't able to keep it / save it.
I'm asking if anyone / everyone would, please, share their toolkit with me. Of course with the understanding I can use it freely.
Thank you.

Re: Register Add - Quick Question
Probably the same way MVS 3.8J did - checked to see if the address was 16M and bailed out of the loop.

Re: Getting NICOF running with VM CE
Both EE and NICOF bypassed strict C runtime library calls, and called CMS low level library routines directly.? Some of those internal interfaces were updated to support BREXX on CMS. I had to update some places where EE called the CMS low level routines, but I did not look at NICOF, which could have similar issues.? Let me know what you have found so far, either on this list or by direct email, and I will see if I can help you get this working. Bob Bolch
On a semi-related topic to the recent TCP/IP discussions, has anyone gotten NICOF () running on VM CE?? ?
I've tinkered with it a bit in the past, but it seems to be setup for some older GCC on CMS conventions, so I haven't gotten it to a state where it cleanly builds on the CP/CMS side.? As I recall, there are some changes required on the java side, but nothing radical.
Any advice or ideas would be welcome.

Re: "Waterloo Tapes" in H390-VM group's Files area
I imagine from a real tape which came with the tapes used to build the original system. From what I remember, and it's a fuzzy memory, the process was that each site that received a copy agreed to make two copies for other sites. So most sites had a copy of the tape.

But where did Bob Abele get his copy from?? :-/
