NAME
  OPEN Statement File Modes

DESCRIPTION
  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.
      o 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.
      o 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.
      o INPUT specifies that the file is opened for sequential input.
      o OUTPUT specifies that the file is opened for sequential output.
      o RANDOM specifies that the file is opened in random-access file mode.
        RANDOM is the default file mode.
