coefficients in different models

Thanks for the suggestion. I just tried it, but I get an error 
message reading "unrecognized command: store"
I tried typing the command after I ran the model, and also including 
at the end of the model statement before running the model, but both 
ways result in error messages. Am I doing something wrong?
