You must be talking about the "foreign" language interface in gretl. In principle I agree it would be "nice to have" also a link to Scilab. Somebody would need to write the glue functions for that, and it's a question of priorities. We cannot promise anything at this point, but would you be ready to cover the Scilab side? What I mean are --for example-- analogues for the "gretl_loadmat" and "gretl_export" functions written in the Octave language (see section 46.2 of the user guide). cheers sven
