PNGJ is not designed to save any settings other than those that are
specifically necessary to define a state. So no user variables, no overall
preferences. You could save a "message" in the state by using the message
command, I suppose, but that would have to be a message that was visible to
the user. Oh, and perhaps in some relatively unused variable such as
set nmrpredictformat "testing messages here"
This would be human- or machine-readable in the state associated with the
PNGJ file if reopened by Jmol.
Although, come to think of it, I think I will remove that from the state.
So don't consider this method supported!
