User sense field

This field is used when the system sense field is set to X'081C'. Byte 2 is not inspected by IMS and, therefore, can contain any value.

Byte 3 contains the hexadecimal identification (X'nn') of the component to which the output message is directed. IMS marks that component as inoperable and continues to send output to other operable components of the workstation. If X'00' or an invalid component is specified, the session is terminated.

IMS binds each session with unconditional bracket termination. This means that both IMS and the workstation go to between-brackets and contention states for all supported sense codes except X'0813' and X'0814'. For these two sense codes, IMS goes to between-brackets and receive states; the workstation goes to between-brackets and send states.
