Hi,
You cannot possibly delete a record in a sequential file. THe DELETE keyword is only of Indexed files,which can be deleted.
Hope this helps. |

HI,
We cannot delete records using DELETE in sequential files but we can logically delete the records.What we can do is we can rewite a record with SPACES. It looks like this
| Code: |
BTECH124 A---
BTECH125 B---
BTECH127 C--- |
TRY THIS
| Code: |
DECLARE A FILE
01 REC.
02 EMPNO PIC X(15).
02----
02----
IN WSS.
DECLARE A "77 EMPLOYEENO PIC A(15). "
ACCEPT EMPLOYEENO.
READ SEQUENTIAL-FILE <eof> /* NOW IT READS ALL RECORDS
IF EMPLOYEENO = EMPNO /*IF CONDITIONS PICKS A REC.
MOVE SPACES TO REC. /* SPACES ARE MOVED TO THAT REC
REWRITE REC. /* NOW REWITING WILL MAKE SPACES |
PLS CHEK
BYE |
