Thank you for the answer. With the condition you'd suggested my problem is solved!

You can't create a list of models as such, in gretl, but you have

the condition

if $coeff[2] < 0 && $coeff[3] > 0

# do something

endif

The "something" might be saving the model specification as a

string, or saving the ID numbers of the X and Z series as

a row of a matrix, or (in the GUI) re-running the estimation

command so as to save a named model, as in

model$i <- ols ...
