Thank you, that is an excellent hack, and I will use it carefully
(though often), but it isn't quite what I had in mind.

In my script called test.R, there is a function called "survey.write",
which writes a report based on some survey results.  It is called
several times at the top level.  I would like the report to say how
"survey.write" was invoked, whether it was invoked as
"survey.write(res.raw,res.q)" or "survey.write(bus.raw,bus.q)".
Obviously I have access to the values of the arguments, but I want the
names of those arguments, or a string containing it all.

Thanks,

 -tom
