Hi Tracy,

It could be slow if your table is big. I would rather use SEEK()
CREATE TABLE SORTTEST (SKNO N(4))
INSERT INTO SORTTEST VALUES (250)
INSERT INTO SORTTEST VALUES (350)
INSERT INTO SORTTEST VALUES (6300)
INSERT INTO SORTTEST VALUES (650)
INSERT INTO SORTTEST VALUES (60)
INDEX ON SKNO TAG SKNO
INDEX ON STR(SKNO,4) TAG SKNOZ
INDEX ON PADR(TRANSFORM(SKNO),4) TAG SKNOA

** When I need to do an incremental search.
nUserinput = 6

SET ORDER TO sknoZ
= SEEK(STR(nUserinput, 4)) ;
		OR SEEK(STR(nUserinput, 3)) ;
		OR SEEK(STR(nUserinput, 2)) ;
		OR SEEK(STR(nUserinput, 1)) 
		
SET ORDER TO sknoA
