Is there a place where one can "Easily" find what the valid values are for
the return codes from API's
And what they mean?    I would suspect there is a correlation between what
is returned in the 10i  return code and the 7 byte ErrorCode.  Right?   Can
one just get alisting by API the valid 10i return codes and a description?
