Syntax:
<label>:                    or                 goto <label>;
  ...                                          ...
  goto <label>;                              <label>:

where <label> is a valid name.
(Note the use of colon instead of semicolon).

While the use 'goto' is discouraged, there are certain things which
are almost impossible (or at least very repetitive) to do otherwise.
The most common use is for error handling:

  if( ferror(fd) ) goto error;
  ...
  if( ferror(fd) ) goto error;
  ...
  return(0);

error:
  err = ferror(fd);
  fclose(fd);
  printf("I/O error #%d \n", err);
  return(err);
 }
