I had a colleague who, likewise within the past decade, declined to use DSN=NULLFILE because of bitter memories of exclusive ENQ conflicts with SYSDSN NULLFILE. I was unable to duplicate his experience, also. It's easy to suspect that at some point in time IBM resolved all such problems by adopting a tactic of converting DSN=NULLFILE to DUMMY early in the JCL conversion process, and that the few (only?) contributor[s] to this thread that maintain (without presenting evidence) that the behaviors differ perhaps have lingering memories of the status quo ante. Perhaps a reader with access to internal historical information can confirm or refute my surmise. -- gil -- StorageTek INFORMATION made POWERFUL -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

In the far reaches there were (IIRC) still UNIVAC 1105's. We were a HQ so we had the "goodies". Before I showed up the unit had (well actiually the entire US Army had been kicked out of France) and there they had 7090's (I THINK my memory can't be trusted on that).. Indeed the "one time" set up was as you suggested was ONE TIME. IIRC we were the only MFT shop in Germany (at least in the Army). There were several dos places for payroll (I think). The civilians that ran the place made a stab at becoming the "world data center". They lost out to dos . I think (rumor) the army decided to go VM (running dos) and all the work that had been done was lost. I never did hear (nor cared) what happened to the UNIVAC machines. Knowing the army they are still running them. I was one of the tech support people for much of the issues. While it wasn't state of the art they were doing some TP (BTAM of 2260's) the batch processing was the center stage. Trying to get money for anything was always a pain. Our GS18 was always taking off to DC to lobby for funds. I can only guess what the army is like now days. But as you indicated (I think) things haven't changed in all this time.

Re: Friday question: How far back is PLO instruction supported?
Probably the biggest customer of this type is the US Government, which includes all of the branches of the Military. Usually, funds are allocated to setup a new system that cover (1) the initial cost of the equipment and software and (2) an (adjustable) maintenance budget for both thereafter. Unfortunately, it's difficult, say for a particular Army base running a personnel system and maybe a few other local applications, to go back in a few years to the Pentagon/Congress to get additional funding to upgrade their hardware (even if it makes better sense in terms of the cost of the hardware maintenance). So, they may have to run for 15 or 20 years with the hardware they got as part of the initial procurement. Now, we could say that as ISVs that supplied software for this system, we'll support what they have, but we won't upgrade them to new releases when they're available. (This way we can avoid having to support the old hardware when we no longer want to.) The problem is, after many years of selling software into this market, you find yourself having to support 47 (or so) different versions of your product. So, instead, if you want to exploit a facility such as PLO in a new version, you take the trouble to dual-path where necessary, and you encourage you customers to stay current with the latest releases. This way, your technical support staff really only needs to be knowledgeable about the most recent few versions. (It takes a little extra effort to test both paths, but as suggested by my code example, it can be made pretty painless with just an enabling bit in a control structure. Moreover, having an alternate path available can be extremely useful in certain troubleshooting scenarios.) This outlines one reason why it can make sound business sense to dual- path. There are others, but perhaps I've already given away too much to those potential competitors out there . --Art Celestini At 01:36 PM 5/28/2005, Craddock, Chris wrote: >> It depends on how backleveled your customers are (might be), and >> how will your products react to an 0C1? > >PLO is now older than dirt.

Re: More Hype for the B1 visas?
Unfortunate, but why should people get into a career path where corporate america is continuing to send their jobs overseas. We need a president that says no more H1B visa's or the like, no more sending american jobs offshore, and all jobs sent overseas during the last 24 years will immediately be brought back home, and corporate america will start paying its employees a decent wage. . Don't even bother telling me about poor little corporate america not being able to compete in a global market when they pay their ceos reidiculous amounts of money. Something's wrong in Denmark when the ceo of a company makes more money than the president of the United States. . "Bank of America Corp. paid its chief executive, Kenneth D. Lewis, $20 million last year as the bank struck a high-profile deal to acquire New England's biggest bank. The pay package, slightly less than Lewis's compensation in 2002, comes as Bank of America eliminates 12,500 jobs nationally as it merges with FleetBoston Financial Corp.. In 2003, the bank said, Lewis received a $1.5 million salary, a $5.4 million bonus, options worth $2.2 million, $10.8 million of restricted stock, and $149,000 of other compensation. The sum includes perks like picking up the $21,000 tab for security at Lewis's house. Though Lewis's $20 million pay sounds high, it is actually in line with the pay of other top executives, said Tony Plath, a professor at the University of North Carolina at Charlotte. Citigroup's chief executive, Sanford Weill, made $44.6 million last year, while the chief executives of Wells Fargo & Co. and Wachovia Corp. made around $16 million and $17 million, respectively. Poor little corporate America, can't compete in a global market, they can only give their ceo $20 million. period. end of comment. - Original Message - From: "Ed Gould" <[EMAIL PROTECTED]> Newsgroups: bit.listserv.ibm-main To: Sent: Sunday, May 29, 2005 7:15 PM Subject: More Hype for the B1 visas?
