S ~S +4: S occupies five devices. Nine characters at most constitute a file name,
3 3 3
including 16#00. If the string does not end with 16#00, the error occurs. If the
ending character is read, the reading of the characters stops, and whether the
file name is legal is checked. The characters which can be used to constitute a
file name are A~Z, a~z, and 0~9. Besides, the file name extension depends on
the file format. The file which is created is in the default folder. If the file name is
"Test1", the characters are written into the devices as follows.
