PLEASE NOTE: Command-line parameters may be specified either by
position or by keywords. An example of the former case is 'sqlldr
scott/tiger foo'; an example of the latter is 'sqlldr control=foo
userid=scott/tiger'. One may specify parameters by position before
but not after parameters specified by keywords. For example,
'sqlldr scott/tiger control=foo logfile=log' is allowed, but
'sqlldr scott/tiger control=foo log' is not, even though the
position of the parameter 'log' is correct.
