OK, thanks--that's the part that wasn't clear.

1) Gretl will generate lags correctly in a panel dataset, entering
a missing value at the start of each time-series.
2) This doesn't really have much to do with Arellano-Bond. A-B is
a method for producing consistent estimates when a panel model
includes lags of the dependent variable. Simply getting the lags
correctly calculated does not produce this effect.
