Hello, this is the ANSI equivalent:
SELECT...
FROM EMPANS A
  JOIN QSTLINK L ON ( L.FLDQUESTION = A.FLDQUESTION)
  JOIN QSTN Q ON (Q.FLDCODE = L.FLDQUESTION)
  LEFT JOIN EMPANS_MEMO M ON (A.FLDCOMMENT =M.FLDREC_NUM)
WHERE L.FLDFORM = ?
    AND L.FLDROLLOVER = 'y'
    AND (Q.FLDINACTIVE IS NULL OR Q.FLDINACTIVE 'y')
