Just a guess..

This can be some file related with Tablebrowse class of clipper...

Pls note that clipper was a command line compiler, so no user interface was avl.. With version 5.0 several utilities were provided like dot.prg (kind of miny dbase where u can run limited dbase commands)..

& Tbrowse class i.e. table browse class..

Pls note that this is just my guess, maybe it is wrong...
