I would guess that the order which these values are returned by getParams
match the order of the parameter declaration in the WHERE clause. Correct?

Hmmm ... how about this:
select * from tbldoc where position('%s' in docnote) > 0
In the above sql, I am trying to select records whose docnote field contains
the parameter string. Let us just suppose that this parameter is set by the
user from a bizobj lookup table. Can one get the parameter value off the
bizobj after the user has set the record pointer of the lookup dataset?
