IF Variables='aty' AND Daegu='yes' THEN SORT=1; ELSE
IF Variables='ah_p' AND Daegu='no' THEN SORT=2; ELSE
IF Variables='ag' AND Daegu='yes' THEN SORT=3; ELSE
IF Variables='a' AND Daegu='no' THEN SORT=4; ELSE
IF Variables='aon' AND Daegu='yes' THEN SORT=5; ELSE
IF Variables='aare_access' AND Daegu='no' THEN SORT=6; ELSE
IF Variables='abehavior ' AND Daegu='yes' THEN SORT=7; ELSE
IF Variables='aty' AND Daegu='no' THEN SORT=8; ELSE
IF Variables='ah_p' AND Daegu='yes' THEN SORT=9; ELSE
IF Variables='ag' AND Daegu='no' THEN SORT=10; ELSE

Try the NOHEADER option on the PANELBY statement.
