| If I am using keyed read, is it possible to update value of key and rewrite the record. |

| No. Rewrite implies that you are updating in place -- that is, THE KEY VALUE DOES NOT CHANGE! If you are changing even a single byte of the key, you MUST use WRITE since REWRITE won't work. |

Welcome!!
Why is there a need at first place to update key, one should never be doing that. This is not a cobol question though.
| Code: |
| For VSAM data sets, you must not change the key field in the record. |

| So, if by mistake I have added a record in file with wrong value of key. So, the only way to correct is to delete the record and insert a new record as we cannot update key value? |

| How many times do you want to hear it? Yes, you must delete the record and write the record with the correct key as you cannot update the key value. Topic locked to prevent further questions -- you have your answer. |
