Sense code 0835

Parameter (with pointer only) not valid: The request contained a fixed- or variable-length field whose contents are not valid or not supported by the NAU that received the request.

Bytes 2 and 3 following the sense code contain sense-code-specific information.
000A
The SLU maximum RU size is not valid.
000B
The PLU maximum RU size is not valid.
nnnn
Bytes 2 and 3 contain a two-byte binary count that indexes (zero-origin) the first byte of the fixed- or variable-length field that has contents that are not valid.
Note: This sense code is not used to report a value that is not valid in an MS major vector. If the value that is not valid occurs in a formatted MS subvector, sense code X'086B' is used. If it occurs in an unformatted subvector, sense code X'0870' is used.
VTAM® hint: Sense code 083500nn indicates that the BIND contains parameters that are not valid and supplies an index (nn) into the BIND that identifies the bytes that the BIND receiver cannot interpret. A buffer trace can provide more problem determination information.
Note: The offset seen in the buffer trace might differ from the offset seen in the IST663I message group and seen by the application.
