Hi,
I need to run fcast command on Vintage Data.


I explain myself.
For the dependent variable, every month there is a new observation and the previous last is changed by revision.
So i need to run a recursive prevision using fcast command, but every time gretl make an estimate ex 01:1991-02:1991-03:1991 the dataset is changing.

Where i can find the fcast command code? Maybe i can try to change it.
Is there some extension for this?
Someone can help me to do this?

Thank you
