ANSI join help

I run this SQL for reportin purposes and it will no longer run since our conversion to SQL 2008. I am a non-technical guy trying to convert a SQL statement to ANSI join syntax.

Any assistance with this conversion is greatly appreciated.

SELECT a.prc_dtl_cd,
a.platts_mo,
b.platts_ind
FROM #platts_prc1 a,
prc_frml_dtl b,
platts_diff c,
platts_diff d
WHERE b.prc_dtl_cd = a.prc_dtl_cd
AND c.mkt_cd =* b.mkt_cd
AND c.merc_ct_mo_cd =* b.merc_ct_mo_cd
AND c.prc_days_cd =* b.prc_days_cd
AND c.platts_mo =* a.platts_mo
AND d.mkt_cd = CASE b.mkt_cd
WHEN 'AGP+-MDCSH' THEN 'AGP+-MDCSH'
WHEN 'ARGUS P+' THEN 'ARGUS P+'
ELSE 'PPLUS'
END
AND d.merc_ct_mo_cd =* b.merc_ct_mo_cd
AND d.prc_days_cd =* b.prc_days_cd
AND d.platts_mo =* a.platts_mo ;
