We helped kill a z/OS to Windows conversion meeting with some simple questions. Q. "This batch process takes 4 hours to run on z/OS. How long would you estimate your converted process would take?" A. "About the same amount of time." Q. "Suppose the process terminates abnormally for some reason after about 2 hours. We get a dump to address the problem and generally fix it from there. Of course, we then need the full 4 hours to run the fixed program. How would this be done on Windows?" A. "Recompile the program with debugging enabled and then single step the program from the command line until the problem occurs." Q. "Are you kidding? Single step the program with the programmer monitoring it?" A. "Yes." --- everybody faints in shock about how long that would take. And how much caffeine and pizza would be consumed. Vendor when everybody revives: "That is why once the conversion is completed and you are running the mainframe apps on Windows, you need to do a business process analysis to change how these processes are done. But that is not covered in this contract." --- some managers have another fainting spell. That is basically what happened. I don't know how Windows people do debugging of an aborted production program. The above does match how I used Turbo Pascal back when I did some minor Windows programming (Win95 time frame). -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
