Excellent - thanks for the solution to this. It's working now!
Please also remember that I have an question outstanding on reviewing -gretl- (even though most of it was comment!)

Some of your regressors have been dropped as redundant, so the list
X that you gave on input does not match in dimension the coefficient
vector. In this case you can use the accessor $xlist to get the list
of actually included regressors (but you have to remove the
constant):
<hansl>
series ai = $ahat
series Xb = lincomb($xlist - const, $coeff[2:])
corr ai Xb
</hansl>
