No decision has yet been made as to how this "communication" will take place.
The solution does not need to survive an IPL, but, if it can be 'PLEX wide that would be even more versatile, but not a requirement., Chuck On Thu, Oct 19, 2023 at 10:03 AM Tony Harminc <[email protected]> wrote: > On Thu, 19 Oct 2023 at 10:18, Charles Hardee <[email protected]> > wrote: > > > > > I will "grossly" explain what I want to do. > > I am not interested in other methods, I have other methods, but I am > > interested in this method the most, if it can be done. > > > > Program A executes and sets a global symbol to a certain value and > > terminates. > > Many other jobs execute and, in each one, as needed, the programs check > to > > see if the global symbol is set and, if it is, to what value. > > They then make logic path decisions within the program based on the value > > of the global symbol. > > Finally, Program B runs, or maybe it's just Program A again, and the > global > > symbol is deleted. > > > > What's the temporal scope for this symbol?
