Re: IBM Development Clueless about COBOL DEV activities
Steve Thompson writes: A migration was proposed to translate (using an IBM utility) an ISV’s code to COBOL (~NOV2013). The problem is, the group that has the translation tool had NO idea about COBOL 5.1, and apparently had no plans to make their tool COBOL 5.1 friendly (as in, NOT using new reserved words and the like). Which IBM utility? If that were true, that doesn't necessarily sound like the end of the world in November, 2013. (Enterprise COBOL 5.1 became generally available in late June, 2013.) It was (and is) as simple as making sure APAR PM85873 is applied to Enterprise COBOL 4.2 then compiling with FLAGMIG4. In the unlikely event there were a problem such as the one you describe (reserved words), that'd catch the problem Then take that translated-to-COBOL code and recompile it with Enterprise COBOL 5.1 right away (or in December, 2013), if you wish(ed). It's COBOL. Apparently the IBM utility only claimed (in November, 2013) that it could translate something into Enterprise COBOL 4.2-compilable code, but so what? Onward and upward, as with every other piece of COBOL code. That's assuming the translation is one time in nature. (See below if not.) Why would a customer want to xlate to COBOL 4.2, and then have to migrate all of that to COBOL 5 in less than 2 years? That'd be awful, wouldn't it? Fortunately it's not true. z/OS 2.1 still runs and supports COBOL code compiled decades ago. If the past predicts the future -- in this case I'd say that's a safe bet -- you can run that 4.2-compiled code decades from now on the then-current release of z/OS. There is no requirement to migrate all of that or even any of that. (Aside: Why is this particular hyperbole so popular? Just stop, please.) When/if you want or need to recompile one particular, specific program (or subset of programs), sure, use the current compiler. If you want to recompile every single line of COBOL source code in your enterprise whenever IBM introduces a new release of its COBOL compiler, Gentoo-style, you can if you wish. You certainly don't have to. I'm not sure where you're getting the in less than 2 years. While I'm an enthusiastic supporter of adopting the latest IBM compiler releases as expeditiously as possible, IBM has not yet announced an End of Service date for Enterprise COBOL 4.2. Since...well, since forever, IBM has introduced core and base technologies first, then supported and exploited those base/core technologies progressively over time. That's true of COBOL, and that's true of every other programming language. Java as well, to pick another example. IBM first introduces a new release of Java, then WebSphere Application Server follows to exploit that new Java release, then middleware products are progressively updated to exploit that new WebSphere Application Server release. IBM support policies provide lots of lifecycle overlap to help customers maintain reasonable release currency. IBM tries to do a reasonable job updating tools and utilities in priority order. For example, if a compiler gets updated then Debug Tool tends to get updated quickly if necessary. Other products (like a certain unnamed IBM migration utility) might take more than 5 months to update (if it even needs updating). Of course, if you're not happy about IBM's schedule, complain!

GRS RESMIL setting on CPU consumption
It is a while since there had been any discussion of appropriate values of RESMIL and its effect on CPU consumptiom. It appears that there was general concensus that RESMIL(OFF) would be a bad idea, and that RESMIL(0) would be best since it should be managed dynamically. In a 3-LPAR plex with GRS linking the 3 (not via VF) then surely whatever happens in one LPAR will happen in the other two, but does that mean that if GRS dynamically sets the RESMIL to 0 it will cause increased CPU consumption in all 3 LPARS? Might it be better to set RESMIL to, say 5 so that it never goes too far down? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Therefore, the low-order three bits of their addresses are zero and can be reused to indicate the type of compressed reference. Of course extra instructions are needed to do shifting to compress and decompress addresses above 4G. Java always chooses the lowest possible shift amount. What's particularly interesting is that IBM benchmarks show a shift amount of 1 on System z is less expensive than higher values while shift amounts 1,2 3 have equal overhead on xSeries pSeries. -- Edward E Jaffe Phoenix Software International, Inc 831 Parkview Drive North El Segundo, CA 90245 http://www.phoenixsoftware.com/ -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Enterprise COBOL v5.1 and RDz v9.x

RDz development might not know that=20 we in COBOL are planning to add support to COBOL =E2=80=A6 SNIPPAGE - Perhaps IBM needs to get the different groups w/in IBM that use the COBOL compiler to be a bit more connected to COBOL development?

A migration was proposed to translate (using an IBM utility) an=20 ISV=E2=80=99s code to COBOL (~NOV2013). The problem is, the group that=20 has the translation tool had NO idea about COBOL 5.1, and=20 apparently had no plans to make their tool COBOL 5.1 friendly (as=20 in, NOT using new reserved words and the like). Can you tell me the IBM COBOL translation utility that was used? I can try to fix this...I know about CCCA, but that one IS updated for COBOL V5, I made sure of that.

Re: IBM Development Clueless about COBOL DEV activities
Let me address a bunch of questions all at once (as much as I am allowed). To my knowledge at this point (as I am writing this) we do not have any lost source. It all matches. It all went through Y2K remediation. We do have a problem with CICS/TS 5.1. We do have a problem with people not fixing their COBOL-II modules to compile with COBOL 4. And so when forced to do it because another department depends on their source... Well, it gets complicated. Now, the utility: We are in the process of replacing COBOL 4 w/ COBOL 5. The drop dead date has not been determined yet. So, we want this utility to produce output that is KNOWN to not cause a COBOL 5 compiler to have problems (Obviously, the utility is NOT a COBOL compiler). I was put in contact with one of the developers, and in my opinion they were actually clueless about COBOL 5. For those of you who think you can run VS/COBOL code forever -- as another person alluded to, RMODE24/AMODE24 code rather causes bottlenecks. It has caused us problems with CICS/TS 5.1. So what is the cost of staying with our COBOL code (COB-II and Ent. COBOL 4)? Well, as we have estimated, it would be the cost of an z/ec12 7xx General CPU (that we had to add to the system 1Q14). And if you are doing the rolling 4 hour We are looking at a reduction in MSUs by compiling with COBOL 5 ARCH(10) OPT(0) of at least 10%. And fixing some threadsafe issues for CICS. There comes a point where throwing money at hardware is no longer cost effective. I have a very different look at things now that I'm doing Cap Tune and not development. I hope I have answered your questions, and justified my argument about cluelessness.

Re: Enterprise COBOL v5.1 and RDz v9.x
As it happens (in my personal view) I agree with you, Tom. But I also agree that IBM should focus first on what its current and prospective customers want. In the fullest meaning of want. That is, I agree with the late Steve Jobs that customers often don't know what they want in large part because they don't know all that's technically possible in the future. I remember a school of thought that thunking might not have been a good idea because it encouraged developers to do what they do best: nothing. :-) That is, developers would use thunking as a means to achieve the bare minimum for a too-timid leap to the next addressing width when what they really should have done (for their customers' and end users' benefit) is brought their whole product/program over to the new width -- or at least continued their efforts in subsequent releases to complete the move to the next width. I don't know if I'd agree with that school of thought, but I remember it, and there's a certain logic to it. I wonder if thunking is an area a third party and/or the open source community would find interesting -- a standard set of callable thunking services. And I wonder if it'd be technically possible as such, and how difficult. Again, in my personal view, I think I'd be mostly satisfied having the popular application environments (CICS TS, IMS TM, WAS, etc.) encouraging reasonably free, ad hoc run-time intermixing of 31-bit and 64-bit programs that interact with each other in myriad ways. That seems to have already happened in several use cases. For example, recent releases of CICS TS support 64-bit Java programs interacting with 31-bit programs written in other languages via all the popular CICS services (COMMAREAs, containers, EXEC CICS LINK, etc.) The 64-bit storage evolution (e.g. containers) has been good, too. I also really like the upcoming COMMAREA/container evolution feature in CICS TS 5.2 (now in open beta) since that's of a similar theme. All good stuff (and only some of the examples). Maybe a bit too orderly and methodical for my occasionally radical nature -- I joke, mostly -- but then again these are often mission-critical applications. Anyway, as always, tell IBM what you want, why, when, and preferably via the right channels.

Re: IBM Development Clueless about COBOL DEV activities
Still wondering which IBM utility. Even if this forum is an unofficial channel, it's hard to fix an unknown gap. To reiterate, if you're still on Enterprise COBOL 4.2 (for whatever reasons), make sure the migration PTF (APAR PM85873) is installed in Enterprise COBOL 4.2 and compile with FLAGMIG4. (You must specify FLAGMIG4 since NOFLAGMIG4 is the default.) Pay attention to what FLAGMIG4 throws, if anything. That'll keep you on the straight and narrow for Enterprise COBOL 5.1. Yes, Enterprise COBOL 5.1 often yields significant performance improvements at runtime. That's an excellent reason to recompile with Enterprise COBOL 5.1. But even that reason is not necessarily a reason to recompile everything. If your primary or only goal is enjoying the performance improvement, start by recompiling your most CPU-intensive programs that run at your highest peak utilization times. The Enterprise COBOL 5.1 compiler can now optimize for specific machine model generations, so it's reasonable to assume you ought to recompile more often -- specifically when the earliest model generation where your code might run is upgraded to a newer model -- in order to pick up that next model generation's performance optimizations. The same basic rule applies: focus on the most CPU-intensive programs that run at your highest peak utilization times.
