**UNFIXFORMAT( **//file//**// )//**

{{blk2blue.jpg|blk2blue.jpg}}

| **UNFIXFORMAT** | Change state of a dynamic file to unfixed |
| //file// | The label of a FILE structure, which must be a reference variable. |

**UNFIXFORMAT** changes a dynamic file that has previously been fixed into an unfixed state, thus allowing you to further change the format.

**UNFIXFORMAT** will set ERRORCODE to NoDriverSupport if you pass a file that was not created with NEW(file)

If you pass a file that was not created using NEW(file), **UNFIXFORMAT** posts the following error codes that can be trapped by the ERRORCODE function:

| **Errorcode** | **Equate** | **Reason** |
| 80 | //NoDriverSupport// | File passed that was not created with NEW(//file//) |
| 47 | //InvalidFileErr// | Structure is invalid |

If error code 47 is posted, the FILEERRORCODE statement can be used to return extended information. See the [[how do i handle an error 47.htm|ErrorCode 47 Extended information]] topic for more information.
