[Gretl-users] Interaction between two variables

Dear Gretl users, I'm trying to introduce an interaction in the next script. ols SPEC const Var1 Var2 COV1 COV2 COV3 COV4 COV5 COV6 COV7 I like to introduce the interaction between Var1 and Var2. What is the correct code? Var1 is a two-levels factor and Var2 is a continuous predictor. SPEC is the response variable and COV1...7 are control covariates. Thank you very much. Regards (And I'm sorry, my English is bad) Juan
