I expect that the following code gives a graph of y. But no graph is shown.

What am I missing? Can you help?

```
var y;
parameters a;
a=0.2;
model(linear);
y=a*y(-1);
end;
initval;
y=10;
end;
steady;
simul(periods = 50);
```

No, you need to add

after the simul command.

Thanks a lot!

Your help means a lot to me at this stage!
