  32 /*  FUNCTION
  33         Write a character to a file handle.
  34
  35         The write is buffered.
  36
  37         If the file handle is an interactive stream,
  38         the buffer is automatically flushed on a linefeed,
  39         carriage return or ASCII NUL.
  40
  41     INPUTS
  42         file      - Filehandle to write to.
  43         character - Character to write.
  44
  45     RESULT
  46         The character written or EOF in case of an error.
  47         IoErr() gives additional information in that case.
  48
  49     NOTES
  50         You should use Flush() when switching between
  51         buffered and unbuffered IO.
