How to deal with non stationary variable?

Hi,

According to the Dynare mannual, the unit_root_vars is now deprecated and will result in no action, so it recommend to the fa200a_steadystate.m in

examples/fs2000 directory. But i can not find it in my computer, and if i find it ,how to use it?

Thanks a lot.

The examples are here:

dynare.org/documentation-and-support/user-guide/models.zip/view

Just trying to figure out the best way of dealing with non-stationarity myself.
