Upgrade 4gl-RDS V.4.0 to V.6.05

I have a problem with this code: ##################################################################### DECLARE c_kst CURSOR FOR SELECT bkto_kto, bkto_ums, bj_belnr, bj_bchtxt, bj_beldate FROM buch_kto, buch_jrn WHERE bj_bchnr = bkto_nr # AND bkto_kto[6,8] BETWEEN v_kst AND b_kst AND bkto_kto[6,8] >= v_kst # v_kst = char(3) AND bkto_kto[6,8] <= b_kst # b_kst = char(3) AND bkto_kto[1,5] MATCHES "?????" ORDER BY bkto_kto[1,5], bkto_kto[6,8],bj_belnr ###################################################################### the table-definition: ###################################################################### create table buch_jrn # Buchungs-Journale ( bj_bchnr serial not null, # laufende Buchungs-Nr. # ... bj_belnr integer not null, # Beleg-Nr. bj_bchtxt char(40), # Buchungstext bj_ums decimal(14,2) not null, # Buchungsumsatz bj_bchdate date not null, # Buchungstag bj_beldate date, # Belegdatum bj_susb smallint, # Anzahl der Sollbuchungen bj_suhb smallint, # Anzahl der Habenbuchungen bj_bchlnr smallint # Buchungslaufnr. am 31.12 ); create index ibjrn on buch_jrn (bj_bchnr); ###################################################################### create table buch_kto # Buchungsverteilung ( bkto_nr integer not null, # Buchungs-Nr. bkto_kto char(8), # Konto-Nr. bkto_ums decimal(14,2) # Betrag H = - , S = + ); create index ibkto on buch_kto (bkto_nr); create index ibuch_kto on buch_kto (bkto_nr,bkto_kto); ###################################################################### With 4GL-RDS Version 4.0 it works fine for more then 8 years. With Version 6.05 the c_kst-cursor isn't sort by bj_belnr.
