If you're talking about BPXBATCH in the "so poor" comment, I'd guess that it was determined to be needed "late in the game". So something was written quickly to get some basic functionality going. It then became enshrined in the temple of backward compatibility. And now, as is often asked, what do we want IBM to stop doing in order to "fix" BPXBATCH to "run reasonably"? IMO, what IBM needs to do is license COZBATCH from Dovetailed Technologies and distribute it with z/OS. There is precedent for this because JZOS (Java) was original a Dovetailed Technologies product. > > > > On 18/10/2017 10:10 PM, Kirk Wolf wrote: > >> Yes, it uses getpwuid() to get your default shell. >> >> But you can run any program with whatever options instead by using PARM= >> see: https://dovetail.com/docs/cozbatch/ref.html >> >> >> >> Kirk Wolf >> Dovetailed Technologies >> http://dovetail.com >> >> On Tue, Oct 17, 2017 at 10:32 PM, David Crayford <[email protected]> >> wrote: >> >> On 18/10/2017 6:10 AM, Kirk Wolf wrote: >>> >>> Yes, it works with bash, but the limitation with bash is that commands >>>> are >>>> never local-spawned.
