                     12: DESCRIPTION    creat_____
                     13: creates a new file or prepares to rewrite an existing
                     14: file called name____;
                     15: name____ is the address of a null-terminated string.
                     16: If the file did not exist, it is given mode mode____;
                     17: if it did exist, its mode and owner remain unchanged
                     18: but it is truncated to 0 length.
                     19: .sp
                     20: The file is also opened for writing, and its file descriptor
                     21: is returned in r0.
                     22: .sp
                     23: The mode____ given is arbitrary; it need not allow
                     24: writing.
                     25: This feature is used by programs which deal with temporary
                     26: files of fixed names.  The creation is done with
                     27: a mode that forbids writing.  Then if a second
                     28: instance of the program attempts a creat_____, an error is
                     29: returned and the program knows that the name is unusable
                     30: for the moment.

                     38: the file does not exist and the directory
                     39: in which it is to be created is not writable; the file
                     40: does exist and is unwritable;
                     41: the file is a directory;
