Compiling 4GL code in RDS 6.00 is not like RDS 4.00

Hello ! I think about upgrade from 4GL RDS 4.x to 4GL 6.00 (and about new server). Now i have many application, which was compiled in 4GL correctly, but i can not compile them in the RDS 6.0 For example, i can not compile this code: DROP TABLE temp_1 LET wherePart = shift1(wherePart) SELECT z.code,z.zname,m.maska,l.tarif,u.name,g.gname, s.servname, l.date_end FROM zone_fn z,OUTER mask_fn m,OUTER(tar_fn l,unit u,grp_conn g,service s) WHERE z.code=m.code_zone AND z.code=l.code_zone AND u.code=l.code_unit AND g.code=l.code_grp AND s.code=l.code_serv INTO TEMP temp_1 LET stText = 'SELECT * FROM temp_1 WHERE ',wherePart CLIPPED, ' ORDER BY ', wherePart1 CLIPPED PREPARE stId1 FROM stText DECLARE c1 CURSOR FOR stId1 | | CURSOR not on SELECT statement. | See error number -363. But when i comment this SQL operator SELECT z.code,z.zname,m.maska,l.tarif,u.name,g.gname, s.servname, l.date_end FROM zone_fn z,OUTER mask_fn m,OUTER(tar_fn l,unit u,grp_conn g,service s) WHERE z.code=m.code_zone AND z.code=l.code_zone AND u.code=l.code_unit AND g.code=l.code_grp AND s.code=l.code_serv INTO TEMP temp_1 all work correctly Thank's for any response
