Vallabhaneni,
The following program will give you the desired results.
| Code: |
IDENTIFICATION DIVISION.
PROGRAM-ID. TESTA
DATE-COMPILED.
ENVIRONMENT DIVISION.
CONFIGURATION SECTION.
INPUT-OUTPUT SECTION.
FILE-CONTROL.
SELECT IN-FILE
ASSIGN TO INFILE
ORGANIZATION IS SEQUENTIAL.
SELECT OUT-FILE
ASSIGN TO OUTFILE
ORGANIZATION IS SEQUENTIAL.
DATA DIVISION.
FILE SECTION.
FD IN-FILE
RECORDING MODE F
LABEL RECORDS ARE STANDARD
BLOCK CONTAINS 0 RECORDS
DATA RECORD IS IN-REC.
01 IN-REC.
05 IN-KEY PIC X(10) OCCURS 5 TIMES.
FD OUT-FILE
RECORDING MODE F
LABEL RECORDS ARE STANDARD
BLOCK CONTAINS 0 RECORDS
DATA RECORD IS OUT-REC.
01 OUT-REC.
05 OUT-KEY PIC X(10).
WORKING-STORAGE SECTION.
01 W-SUB PIC 9(1).
01 S-IN-FILE PIC X(1) VALUE 'N'.
PROCEDURE DIVISION.
PERFORM 1000-INITIALIZATION
PERFORM 2000-MAIN-PROCESS UNTIL S-IN-FILE = 'Y'
PERFORM 3000-WRAPUP
GOBACK
.
1000-INITIALIZATION.
*************************************************************
* THIS PARAGRAPH OPENS INPUT AND OUTPUT FILES AND DOES THE *
* PRIME READ. *
*************************************************************
OPEN INPUT IN-FILE
OUTPUT OUT-FILE
PERFORM 2100-READ-IN-FILE
.
2000-MAIN-PROCESS.
*************************************************************
*THIS PARAGRAPH PERFORMS THE MAIN LOGIC *
*************************************************************
PERFORM VARYING W-SUB FROM 1 BY 1 UNTIL W-SUB > 5
MOVE IN-KEY (W-SUB) TO OUT-KEY

MOVE SPACES TO OUT-REC
END-PERFORM
PERFORM 2100-READ-IN-FILE
.
2100-READ-IN-FILE.
*************************************************************
*THIS PARAGRAPH READS THE IN-FILE *
*************************************************************
READ IN-FILE
AT END
MOVE 'Y' TO S-IN-FILE
END-READ
.
3000-WRAPUP.

Vallabhaneni,
I moved the other topic to the similar topic. Please post all your similar queries in one forum.
Hi All,
I am moving records from input file to output file.One filed in input file having 8 times occurs but I need only five times in output.
Input Record 1
| Code: |
01 file1 pic x.
01 filed2 pic 9.
01 field3 pic 9(2).
01 field4 occurs 8 times indexed by field.
05 code1 pic 9(3)
88 value1 '111'
88 value2 '112'
|
Output record
| Code: |
01 filed pic x.
01 filed pic 9.
01 field pic 9(2).
01 field occurs 5 times indexed by fiel
05 code2 pic 9(3).
88 value1 '111'
88 value2 '112"
|
Can you help me how can I control in between moves i.e
move filef1 to field
move field 2 to field
PERFORM VARYING field +1 BY +1
UNTIL field GREATER +8
MOVE code1 (field) TO code2(field)
SET fiel +1
end-perform.
This will write 8 occurances frim input to output I need a put a contol to get only five occurances.
When I am in editing screen it is ok,when I did hit submit button after thet when I go to preview page it is not showing properly.
Thanks |

Vallabhaneni,
If you want only 5 occurances in the output file then control the perform for only 5 times. Change your perform statement to the following and and you don't need an explicit SET command to increment the counter.
| Code: |
PERFORM VARYING field +1 BY +1 UNTIL field > 5
MOVE code1 (field) TO code2(field)
End-perform.
|
I suggest you read the cobol manual to get a clear idea of OCCURS AND GROUP MOVES

Hope this helps...
