Thank you both, Marco and Ben Fritz, for your info. I had interpreted FileChangedShell to mean that if I had a buffer for img.dat in vim, I could automatically read its update into another buffer exactly where I want the new data to end up. In other words, completely effortless on my part.

The img.dat buffer is duly updated, but the r command to read it into the active buffer does not operate. Can it be done?
