The CLI Request Control Block (CLI2RCB) is an internal control block used to maintain the context of a request. When a request is posted to a session, an RCB is created to contain the request identifiers, the request state, and pointers to the request and response buffers associated with the request. The RCB is inserted in a queue of RCBs attached to a session’s SCB.
