Hi Steven,

- i suppose it is a queue.
- i suppose you want process with FIFO rule

pseudocode

SELECT queue
SET ORDER TO FIFOORDER
SCAN
 <save> fieldExp <into> duplexExp
 STORE RECNO() TO iRec
 LOCATE FOR fieldExp< equal to >duplexExp
 IF RECNO()#m.iRec
     DELETE RECORD m.iRec
 ELSE
     GO m.iRec
 ENDIF
ENDSCAN
