.ls parameter
Parameter to be return.  Definitions in nlfit.h are:

.nf
NLNPARAMS	integer		# Number of parameters
NLNFPARAMS	integer         # Number of fitted parameters
NLITMAX		integer		# Maximum number of iterations
NLITER		integer		# Current number of iterations
NLNPTS		integer         # Number of points
NLSUMSQ		real/double	# Current reduced chi-squared
NLOLDSQ		real/double     # Previous reduced chi-squared
NLLAMBDA	real/double     # Value of lambda factor
NLTOL		real/double	# Fitting tolerance in %chi-squared
NLSCATTER	real/double     # Mean scatter in the fit

DESCRIPTION
The values of integer, real or double  parameters are returned.
The parameters include the number of parameters, the number of fitted
parameters, the maximum number of iterations, the number of iterations,
the total number of points, the current chi-squared, the previous
chi-squared, the lambda factor, the fitting tolerance and the fitted
scatter term.
