Choosing variables to save simulation

Can I choose which variables I want the simulation to save data for? Or is it an all or nothing option?

Saved where? And yes, currently it is an all or nothing option. Why would you like to change this?

If you have lots and lots of variables, sometimes interest lies on only one or two.

That is currently not possible. Dynare will always simulate all variables. Saving them or not should make no difference. If you want to speed up your code, you can change stoch_simul you can comment out the

command that writes the simulation into variables with their respective name. The simulated series can be accessed in

which always contains all variables for Dynare decision rule design reasons.
