Following is a brief description of the secondary error codes for error 98s for the Vision file system.
| 01 | The file size listed in the file's header does not match the actual file size. |
| 02 | The header's next record pointer points to an area that is invalid. |
| 03 | Unique ID used to distinguish duplicate keys has already been used and cannot be used with a new key. |
| 04 | Missing tree terminator key. |
| 05 | An error was detected while performing a bulk read of a record. |
| 06 | The key being deleted from the tree was not found in the tree. |
| 07 | A child node was not found in its parent. |
| 08 | An I/O error occurred when the runtime was trying to read key information out of the file's header. |
| 09 | A pointer in a node points past the end of the file. |
| 12 | A node in the free node list was not marked as a free node. |
| 13 | A record in the deleted record list was not marked as a deleted record. |
| 20 | Non-zero key prefix on first key in node. |
| 21 | Key prefix larger than key size. |
| 22 | Key prefix or key size larger than maximum key size. |
| 23 | An invalid value was found while reading the key parameters in the header. |
| 31 | A record pointer in a Vision Version 3 file points to a record-chain value. In a Version 3 file, record pointers should always point to the start of a record, never to a record-chain value. |
| 42 | The unique record counter has been exhausted. Rebuild the file to correct the error. |
| 68 | A Vision 4 or 5 data segment is not found during an open. |
| 69 | A Vision 4 or 5 index segment is not found during an open. |
| 81 | Invalid data found in record header when a compressed record was read. |
| 82 | Invalid data found in record header when a non-compressed record was read. |
| 83 | When a record was read, an I/O error occurred or the record was too short. |
| 84 | When a record link was read, an I/O error occurred or the link was too small. |
| 85 | Record contains invalid record compression codes--the record would uncompress into a record that was larger than the maximum record size. |
| 86 | During a record write, a read of a record-chain value failed, probably due to an end-of-file condition. |
| 87 | Vision Version 4 or 5 detects that it is about to write a record to an area of a file that does not contain an appropriate record header. An appropriate record header indicates that a record currently does not exist at this address. |
| 89 | In Vision Version 4 or 5, on open, a data segment's internal revision number does not match the internal revision number stored in the header of the first data segment. |
| 90 | In Vision Version 4 or 5, on open, an index segment's internal revision number does not match the internal revision number stored in the header of the first data segment. |
| 97 | A vutil -key operation did not complete successfully. |
| 99 | Vision Version 4 or 5 has tried to open the 65,537th data or index segment for this file. Vision can only support 65,536 data segments and 65,536 index segments per logical file. |
