How to delete or edit a record from a file?

[Goenitz]

i m a beginner who had wrote codes to write records into a *.dat file and can also read from a file.
So in my menu i wish to create extra options to delete and edit records. Can anyone help me by providing my some sample codes or the logic behind it.

The file record in the file section is:

01 CUSTOMER-REC.
02 CUSTOMER-NAME PIC X(20).
02 STREET-NO PIC X(25).
02 CITY-STATE-ZIP PIC X(25).
02 CREDIT-PUR-AMT PIC 9(6)V99.
02 NO-OF-PAYMENTS PIC 9(2).

To delete record: study the DELETE verb.

To edit record: study the REWRITE verb.

If you haven't studied indexed files yet, you need to read about indexed files. 99.9 percent of DELETEs and REWRITEs are applied to indexed files.

Good luck! Tom Morrison
