SET PROCEDURN TO SP S = 0

DO SP1 WITH 5 , S ? S

SET TPROCEDURE TO RETURN * SP PRG PROCEDURE

PARAMETERS X , Y N = 1 Y = 1

DO WHILE N < X Y = Y + N

N = N + 1

ENDDO

RETURN

8、以下程序运行结果是

SET TALK OFF DIMENSION X (2 ,2) X = 5

FOR I = 1 TO 2 FOR J = 1 TO 2 IF I = J X (I , J ) ENDIF

?? X (I , J) ENDFOR ENDFOR

SET TALK ON RETURN 二、完善程序

1、下列程序计算机 S =1！+ 2！+3！+4！+5！中，填空完成程序。 S = 0

FOR N = 1 TO 5

FOR I = 1 TO N P = P * I ENDFOR

ENDFOR ? “SUN =” , S 2、用下列程序找出所有的水仙花数，所谓水仙花数，是指这样一

个三位数，其各位数字的立方和等于该数本身，如 153 = 1^3 +5^3 +3^3，对以下程序填空完成该功能。 FOR N = 100 TO 999 A = INT ( N / 100) B =

C = N – INT (N / 10) * 10 IF N = A^3 +B^3 +C^3 ? N ENDIF ENDFOR RETURN 3、将新表 DB2 . DBF 文件中学号重复的记录删掉（只保留一个） SET TALK OFF SET SAFETY OFF
