I would like to report a small bug with the assignment operator:

The script below contains one of the NLS examples in the gretl users
guide (Davidson):

<script>
open ects_nls.gdt
ols y 0 x1 x2 --vcv
genr alpha = $coeff(0)
genr beta = $coeff(x1)
genr a0 = alpha
genr b0 = beta

# with analytical derivatives
mod1 <- nls y = alpha + beta*x1 + (1/beta)*x2
 deriv alpha = 1
 deriv beta = x1 - x2/(beta*beta)
end nls --vcv
</script>

In line 4 from the bottom I modified the example writing the assignment
operator '<-' so that the NLS model should be saved in the session and
be available as 'mod1' in the icon view. The problem is that now if I
click on mod1 in the icon view, I see that the saved model is not the
NLS but the OLS.

(gretl from CVS built on 2010-03-24, running on Ubuntu Linux 9.10)
