The APPEND, BINARY, INPUT, OUTPUT, and RANDOM keywords are used in the
OPEN statement to specify file modes. INPUT, OUTPUT, and RANDOM are also
used in the OPEN COM statement.
 
    - APPEND specifies that the file is to be opened for sequential output
      and sets the file pointer to the end of the file. A PRINT # or
      WRITE # statement then extends (appends to) the file.
    - BINARY specifies a binary-file mode. In binary mode, you can read or
      write information to any byte position in the file using GET or PUT
      statements.
    - INPUT specifies that the file is opened for sequential input.
    - OUTPUT specifies that the file is opened for sequential output.
    - RANDOM specifies that the file is opened in random-access file mode.
      RANDOM is the default file mode.
