LOCAL i As Integer, n As Integer, lcOut As String
CLOSE DATABASES ALL
CLEAR
CREATE CURSOR nums (num I)
INDEX ON num TAG num COLLATE "Machine"
SET ORDER TO 0
n = 50
RAND(-1)
FOR i = 1 TO n
    INSERT INTO nums VALUES (RanInt(1, 10))
ENDFOR
SELECT num, COUNT(num) As cnt FROM nums ;
GROUP BY num INTO CURSOR grouped
LIST OFF TO FILE grouped.txt NOCONSOLE
lcOut = ""
SCAN
    lcOut = lcOut + TRANSFORM(num) + ","
ENDSCAN
lcOut = LEFT(lcOut, LEN(lcOut)-1)
? lcOut	

FUNCTION RanInt(tnLow As Integer, tnHigh As Integer) As Integer
RETURN INT((tnHigh - tnLow + 1)*RAND() + tnLow)
ENDFUNC
