[Gretl-users] Checking for lagged endogenous terms

Hi, is there a way to find out with script programming if and how many lagged endogenous terms have been included in a single equation estimation? The background is that I want to write a function doing some forecasting-related stuff (beyond what's already built in), using the results in the $model accessor. In an equation system in gretl I'd say it's possible to get this information by looking at $sysA (in combination with $ylist). Similarly in a VAR/VECM. But in a single equation? I think internally gretl "knows" about the lags already, or it couldn't do forecasts properly. The question is how to get this information via hansl scripts. thanks for any hints or workarounds, sven
