Re: [Gretl-devel] how do packages in a model window grab the $model bundle?

But it's straightforward: in your GUI interface function, just grab hold of $model and pass it to the function that actually does the business. I have an example that I was planning to share in the "code sprint" -- here's its "GUI main": function bundle GUI_exogtest (int xvar[$mylist] "regressor to test") matrix ds = exogtest($model, deflist(xvar)) return defbundle("test", ds[1], "df", ds[2], "pvalue", ds[3]) end function Besides illustrating use of $model there's a second novelty here: the int "xvar" argument has a default value of "$mylist". This requires that the gfn spec designates a "list-maker" function, as in list-maker = exogtest_listmaker Then the list-maker function will be invoked automatically to populate a drop-down selector showing names of series, and the value received for "xvar" will be the ID number of the series selected by the user. I might as well attach the whole script for this forthcoming package so you can get the context. It implements the "diff in Sargan" test for exogeneity of a particular term in a TSLS model. Allin
