I have searched my manuals, but to no >avail. DOS uses file handles 0-4 for special devices (I believe it is standard input, standard output, standard error, auxiliary device, and standard printer). Other than that, you get the file handle when you issue a create or open function call, and this is what you use when you call function 40h to write to a file.
