 Dear Professors,
 Please, I need you to put me through on two things.
 First, how can I save a correction matrix using hansl syntax. 
check out mcorr()
 Secondly, I want to perform a forecasting after estimating through 
 maximum likelihood. For example, as shown below,
 mle ll = "likelihood function"
 series e = GDPrate  -  constant
 params constant
 end mle
 
Are you sure you need explicit MLE? At least in these linear cases OLS 
is MLE.
 If I want to perform the dynamic forecast or one step ahead forecast,
 what is the additional syntax needed. 
Look at the 'fcast' command and the documentation. If anything remains 
unclear, feel free to ask again.
cheers,
