In fact, the shortcut of "we'll assume a .gdt suffix if no suffix is given" is confined to data files that are supplied with gretl. I guess that should be clarified in the doc.

I now see that my reply was incorrect, but that facility was designed to work for supplied data files and it does have to do with path location. Your failing "dummyfile" example works for me if the gdt file in question is saved to my gretl "workdir", or to gretl's "data/misc" directory, but not otherwise.
