Even if you stay with the 'old' SCAN command, you should use all its 
possibilities (capabilities ?) :

SELECT EDIHDR SCAN FOR SEEK('TARGE'+edihdr.CUSTPO, 'orderhdr')
         SELECT OrderHdr
         * if you had a good index, you could have a fine SCAN REST WHILE a lot 
quicker

        * than the SCAN REST FOR
        SCAN REST FOR account+custpo+order = 'TARGE'+edihdr.CUSTPO
                SELECT EDILN
                SCAN FOR ORDER+STYLE+COLOR+STORE= OrderHdr.order ;
                  AND !EMPTY(mstrupcno) AND ;
                   SEEK(OrderHdr.order+EDILN.STYLE+ EDILN.COLOR+EDILN.STORE, 
"orderln") ;
                    AND EMPTY(xxxx.mstrupcno)
                         SELECT OrderLn
                         REPLACE mstrupcno WITH EDILN.MstrUpcNo , ;
                                    MstrUpcQty WITH EDILN.MstrUpcQty, ;
                                    MstrUpcPrc WITH EDILN.MstrUpcPrc
                        ENDIF
                ENDSCAN
        ENDSCAN
ENDSCAN

I haven't test it and there is a logical problem with EMPTY(mstrupcno)
