Not sure your question-
by script to you mean ".scr" files? Those can be read by only AutoCAd.
or do you mean can Fortran or Basic routines be called by a ".scr" file? I'd say no, script files are just a series of AutoCAD commands.
Do you mean, can Fortran or Basic be used to automate Autocad? not that I've heard; but AutoCAD arx applications are developed with C++ or similar, and VBA can be used for some applications, although I believe that is getting phased out.
