Most -- probably all -- of these would work fine, if keeping all of the information internal to the process. However, we have a couple of monitoring programs that provide us with information about other PxPlus processes. When we were using nthost/ntslave, we were able to provide a unique machine ID on the command line that we could parse out. With SimpleCS, all of the ID's come through as T0, and that's how they show up on the server side, even when we change the process's FID(0) once we start up. By changing the FID(0) before the WindX connection is established, the id=T0 is overridden.
Just looking for a clean way to establish that without having to touch 100+ machines around the country.
