Hello, 
Thanks for the help. This isn't really going to work for me. I'm doing a batch
process. I read the file back into my program a little later so using the fit
file makes life much more complicated. I posted the same question on Google
Groups
(http://groups.google.com/group/comp.graphics.apps.gnuplot/browse_thread/thread/72184d33cee34185/74dadb9c6ae490bb#74dadb9c6ae490bb)
and got another reply that was much more feasible. I've posted Theo  Hopman's
response below:

This method also shouldn't save any information about variables, since 
you're asking it to save functions. If you do 
set fit errorvariables 
fit ... 
save variables 'var.dat' 

you'll have (all) variables, including fit parameters and their 
estimated errors in the file 'var.dat'.

Thanks again Hernán!
Chris
