读取索引文件（COBOL）时出现问题
|
我在围绕读取索引文件的程序中遇到了一个大问题。尽管该程序还涉及其他两个有效的读取，但该读取一直给我带来问题。这是涉及它的所有代码：
SELECT PO-MASTER-FILE
ASSIGN TO \'PO-INDEXED.DAT\'
ORGANIZATION IS INDEXED
ACCESS IS RANDOM
RECORD KEY IS PO-KEY
FILE STATUS IS FILE-STATUS-CODE.
DATA DIVISION.
FILE SECTION.
FD PO-MASTER-FILE.
01 PO-MASTER-RECORD.
05 PO-KEY.
10 PO-VEND-NUMBER-M PIC X(4).
10 PO-ORDER-ID-M PIC X(8).
WORKING-STORAGE SECTION.
05 PO-KEY-S.
10 POLI-VEND-NUMBER-S PIC X(4).
10 POLI-ORDER-ID-S PIC X(8).
SCREEN SECTION.
05 LINE 07 COLUMN 23 VALUE \'NUMBER:\'
FOREGROUND-COLOR 10.
05 LINE 07 COLUMN 50 PIC X(4)
USING POLI-VEND-NUMBER-S
FOREGROUND-COLOR 15 AUTO.
05 LINE 08 COLUMN 23 VALUE \'ORDER ID:\'
FOREGROUND-COLOR 10.
05 LINE 08 COLUMN 50 PIC X(8)
USING POLI-ORDER-ID-S
FOREGROUND-COLOR 15 AUTO.
PROCEDURE DIVISION.
100-MAIN.
OPEN I-O POLI-MASTER-FILE
PO-MASTER-FILE
ITEM-MASTER-FILE
PERFORM 120-DISPLAY-SCREEN
UNTIL FUNCTION-CODE-S = \'END\' OR \'end\'
CLOSE POLI-MASTER-FILE
PO-MASTER-FILE
ITEM-MASTER-FILE
EXIT PROGRAM
STOP RUN.
120-DISPLAY-SCREEN.
****
MOVE FUNCTION-CODE-S TO SAVE-FUNCTION-CODE
****
MOVE POLI-VEND-NUMBER-S TO SAVE-VEND-NUMBER
****
CALL \'DATETIME\' USING DATE-TIME-PASS-AREA
DISPLAY SCREEN-IMAGE
ACCEPT SCREEN-IMAGE
IF FUNCTION-CODE-S = \'END\' OR \'end\'
CONTINUE
ELSE
PERFORM 200-PROCESS
END-IF.
200-PROCESS.
MOVE SPACES TO ERROR-MESSAGE-S
EVALUATE TRUE
WHEN FUNCTION-CODE-S = \'INQ\' OR \'inq\'
PERFORM 300-INQUIRY
WHEN FUNCTION-CODE-S = \'ADD\' OR \'add\'
PERFORM 400-ADD
WHEN FUNCTION-CODE-S = \'CHG\' OR \'chg\'
PERFORM 500-CHANGE
WHEN FUNCTION-CODE-S = \'DEL\' OR \'del\'
PERFORM 600-DELETE
WHEN OTHER
MOVE \'Invalid Function Code\' TO ERROR-MESSAGE-S
END-EVALUATE.
400-ADD.
****
PERFORM 900-VALIDATE-THE-FIELDS THRU 999-EXIT
IF ERROR-MESSAGE-S = SPACES
PERFORM 420-OK-TO-ADD-THE-RECORD
ELSE
****
MOVE SPACES TO POLI-DATE-ADDED-S
END-IF.
900-VALIDATE-THE-FIELDS.
MOVE PO-KEY-S TO PO-KEY
READ PO-MASTER-FILE
INVALID KEY
IF FILE-STATUS-CODE = \'23\'
MOVE \'Vendor Number Or Order ID Is Not Found\'
TO ERROR-MESSAGE-S
GO TO 999-EXIT
ELSE
MOVE FILE-STATUS-CODE TO UNEXPECTED-CODE
MOVE UNEXPECTED-CODE TO ERROR-MESSAGE-S
END-IF
END-READ
POLI-VEND-NUMBER-S
POLI-ORDER-ID-S

FD PO-MASTER-FILE. 01 PO-MASTER-RECORD. 05 PO-KEY. 10 PO-VEND-NUMBER-M PIC X(4). 10 PO-ORDER-ID-M PIC X(8). 05 PO-DATE-ADDED-M. 10 PO-DA-YEAR-M PIC X(4). 10 PO-DA-MONTH-M PIC XX. 10 PO-DA-DAY-M PIC XX.
