Dear

PUBLIC NAME1,OBMARKS,TOTMARKS
STORE SPACE(30) TO NAME1
STORE 0 TO OBMARKS,TOTMARKS

CREATE TABLE Master1 (NAME1 C(10), OBMARKS N(4),TOTMARKS N(4))
INSERT INTO Master1 (NAME1,OBMARKS,TOTMARKS) VALUES ("A",400,850)
INSERT INTO Master1 (NAME1,OBMARKS,TOTMARKS) VALUES ("B",685,850)
INSERT INTO Master1 (NAME1,OBMARKS,TOTMARKS) VALUES ("C",700,850)
INSERT INTO Master1 (NAME1,OBMARKS,TOTMARKS) VALUES ("D",200,850)
INSERT INTO Master1 (NAME1,OBMARKS,TOTMARKS) VALUES ("E",279,850)
INSERT INTO Master1 (NAME1,OBMARKS,TOTMARKS) VALUES ("F",510,850)

Test = "csr" + SYS(2015) && gives you unique cursor name everytime
SELECT *,;
TRANSFORM((OBMARKS/TOTMARKS)*100,"##.##") AS PERCENTAGE;
FROM Master1;
ORDER BY PERCENTAGE DESCENDING;
INTO CURSOR XYZ

SELECT XYZ
BROW

I hope this will help
