Hex Long Floating Point REXX
Hi @ll, has someone ever tried to extract fields SMF30DDS and SMF30DDR (long floating point hex) or any field in REXX? There are a couple of F2something routines out there but it seems that none of them produce the right value. Has somebody a REXX example for me? Anything would be very appreciated since it might bring me further. Thx in advance.

I guess you could call it hacking. Or just using a wide-open system :-) The user would need: - network access to the FTP and listen port - firewalls could prevent - the TCP stack could limit (TERMINAL, SERVAUTH, etc) - access to FTP and ability to upload an executable file - an FTP exit could be used to prevent either - permission to submit a job SAF and/or a FTP exit could limit this - job would need permission to listen on a port - user could be prevented from running a shell default program in OMVS segment Kirk Wolf Dovetailed Technologies http://dovetail.com On Sat, May 18, 2013 at 3:17 PM, John McKown john.archie.mck...@gmail.comwrote: http://mainframed767.tumblr.com/post/50574743147/big-iron-back-door-maintp-part-two basically the person must be able to ftp into a UNIX subdirectory and to submit a job.

Re: Hex Long Floating Point REXX
There is plenty of C and PL/I support available for BFP. Having a brain rotted by excessive exposure to assembly language, I would thus use the conversion machine instructions THDER, THDR, TBDER, and TBDR to move back and forth between HFP and BFP. As yet there are no conversion instructions for HFP==DFP or even BFP==DFP; but they are, I suspect, in the womb of time, perhaps indeed nearly at term.

In the Python script that a link in that site points to, I see that one line, 525, is over 202000 bytes long, assigning a string literal about that long to a variable.

Re: JOB: z/OS Systems Programmer @ Univ. of FL
Watch out for the speed traps in the area, e.g. Waldo and Lawtey, Florida. One of the benefits is likely to be the ability to take courses at the University at no charge. Bus rides are free on Gainesville's RTS with a staff ID, which means you may be able to convert from a two car household to a one car household (for example). There's affordable preschool (Baby Gator). Staff can use all the UFL facilities (e.g. library, tennis courts, etc.) generally free of charge. UFL pays for a certain number of children of employees to attend free of charge. Property taxes tend to be low in Florida, although that might mean a challenge finding good schools. (I'm not sure about the area around UFL.) Florida has a homestead exemption which is quite interesting and which still offers some protection in bankruptcy (O.J. Simpson is familiar). Florida was hit very hard in the mortgage/financial crisis and hasn't really recovered, so some parts of the state offer very affordable real estate. Employment at UFL is likely to be fairly stable, and working hours are likely to be reasonable. As mentioned there's no state income tax, and the sales tax rate in and around Gainesville is 6%. The local job market is not terribly strong, so you'll probably want to be prepared to move again if you leave UFL for other employment. Gainesville has an airport (GNV) which American, Delta, United, and U.S. Airways serve to/from their hub cities in the region. The city's elevation is high by Florida standards (151 feet), and it's inland so not too badly affected by hurricanes. Local flooding could still be a problem. Tornados are possible, but that's true in much of the U.S. A weather radio and a storm shelter are recommended. Ice storms sometimes occur in the winter, and its gets hot and humid in the summer. If you're looking for a position I'd seriously investigate that one. It looks fairly compelling.

Re: Predict WLC invoice amount ...
Words have meaning. ...Which probably at least reduce the intensity... almost never means *zero* worry. Why else would I have typed those words? Let's try again. Enterprise License Agreements (ELAs) still require SCRT collection and submission. I didn't claim otherwise. How much you worry about those monthly reports -- the intensity of worry -- will depend in large measure on your caps relative to your utilization. I strongly disagree with the statement that Tails IBM wins, heads you lose with ELAs. The ideal case is that you choose caps (a utilization forecast) that are exactly as you experience. However, if you don't -- if you're either too high or too low -- YOU STILL ENJOY ELA BENEFITS! You haven't *maximized* those benefits, but you still come out way ahead unless you've totally screwed up. It's a gamble, but the odds of winning that bet are HEAVILY weighted in your favor.
