Btw, the solution I came up with was to write an external "my_function.pro" file from within "my_procedure", before calling NEWTON. Something like this:

openw, outunit, '/.../my_function.pro', /get_lun
printf, outunit, 'function my_function, x'
printf, outunit, 'c1 = ', c1
printf, outunit, 'return, x^2 + 5*x - c1'
printf, outunit, 'end
close, outunit & free_lun, outunit'

But this just doesn't feel right... and I run into another problem, as you can see from my previous post:

Thanks again,
