I did a quick test. The simplest way was to simply have two SELECT
sentences which reference the same DD.
FILE-CONTROL.
SELECT FB ASSIGN TO UT-S-INPUT
FILE STATUS IS FB-STATUS-1
.
SELECT VB ASSIGN TO UT-S-INPUT
FILE STATUS IS VB-STATUS-1
.
...
FILE SECTION.
FD FB
RECORD CONTAINS 80 CHARACTERS
RECORDING MODE IS F
BLOCK CONTAINS 0 RECORDS
LABEL RECORDS ARE OMITTED
.
01 FB-RECORD.
05 CARD-IMAGE PIC X(80).
FD VB
RECORDING MODE IS V
RECORD IS VARYING IN SIZE
FROM 1 TO 80 CHARACTERS
DEPENDING ON VB-LRECL
BLOCK CONTAINS 0 RECORDS
LABEL RECORDS ARE OMITTED
.
01 VB-RECORD.
05 CARD-COLUMN OCCURS 1 TO 80 TIMES
DEPENDING ON VB-LRECL
PIC X(1).
...
PROCEDURE DIVISION.
...
OPEN INPUT FB
IF FB-FILE-STATUS-1 IS NOT 00 THEN
OPEN INPUT VB
IF VB-FILE-STATUS-1 IS NOT 00 THEN
DISPLAY 'CANNOT OPEN INPUT FILE.'
MOVE 8 TO RETURN-CODE
GOBACK
END-IF
ENDIF
...
IF FB-FILE-STATUS-1 IS ZERO THEN
READ FB-RECORD
MOVE FB-RECORD TO WS-RECORD
ELSE
READ VB-RECORD
MOVE VB-RECORD (1:VB-LRECL) TO WS-RECORD
END-IF
... process data in WS-RECORD

Wasn't there something about a PASCAL programmer knowing the value of
everything and the Wirth of nothing?
