END FUNCTION
Output is
12. Rewrite the given program after
correction the bugs:
OPEN “XYZ. REC” FOR INPUT AS #4
CLS
INPUT “Enter post to be searched”; s$
FLAG=0
WHILE NOT EOF (1)
INPUT 1, N$, P$, D$, S
IF UCASE (S$) = UCASE$(P$) THEN
PRINT N$, P$, D$, S
FLAG=1
END IF
WEND
correct program
OPEN “XYZ. REC” FOR INPUT AS #1
CLS
INPUT “Enter post to be searched”; s$
FLAG=0
WHILE NOT EOF (1)
INPUT #1, N$, P$, D$, S
IF UCASE$ (S$) =
UCASE$(P$) THEN
PRINT N$, P$, D$, S
FLAG=1
END IF
WEND
IF FLAG=O THEN PRINT “Data not found”
CLOSE#1
END
13. Study the following programs and
answer the given question:
DECLARE FUNCTION STRING (S$)
CLS
INPUT
“Enter any string = “;s
PRINT
“Total number of alphabet a = “; STRING (S$)
END
FUNCTION
STRING (S$)
FOR
I = 1 TO LEN (S$)
C$
= UCASE$ (MID (S$, I, 1))
IF
C$ = “A” THEN
COUNT
= COUNT +1
END
IF
NEXT I
STRING = COUNT
END FUNCTION
a. For what purpose UCASE$ is used?

R=N MOD
10
C=C+1
S=S+R
N=N\10
WEND
PRINT
"TOTAL NUMBER OF DIGIT";C
PRINT
"SUM OF DIGIT";S
END SUB
