Hi,
I remember there is a way in IDL where one can pass parameters
indirectly; that is, if procedure A calls procedure B which then
calls procedure C, pass parameters from A to C without modifying
the procedure call in B. Specifically I need to pass extra
parameters to a function called by CURVEFIT. I looked over the
manual but could not find a reference; could someone tell me how
to do this?

I had to do a similar thing with CURVEFIT and found a somewhat simple
solution. By examining the CURVEFIT procedure, I found that it just
passed along *blindly* the "X" variable
( as in Result = CURVEFIT(X, Y, W, A [, Sigmaa]) )
to the function procedure (FUNCT). Thus if you need to pass extra data
to FUNCT you can just pack it into X before you call CURVEFIT. Then
inside your FUNCT, you can unpack X into separate variables.
I hope that is understandable and answers your question.
