I am afraid it is no help today but, in case you haven't found it, the Show Properties() function shows all of the messages you can send something and is usually great for this sort of thing:

```
Names default to here( 1 );
dt = Open( "$Sample_data/iris.jmp" );
genreg = dt << Fit Model(
Y( :Sepal length ),
Effects( :Sepal width, :Petal length, :Petal width ),
Personality( "Generalized Regression" ),
Generalized Distribution( "Normal" ),
Run(
Fit(
Estimation Method( Standard Least Squares ),
Validation Method( None )
),
Fit( Estimation Method( Lasso( Adaptive ) ), Validation Method( AICc ) )
)
);
genreglasso = (genreg << XPath("//OutlineBox[text()='Adaptive Lasso with AICc Validation']"))[1];
Show properties(genreglasso << Get scriptable object);
```
