Relationship to POST=RESP

The exception to the preceding description occurs when a response is received that completes the posting of an outstanding POST=RESP output operation. In this case, the input RH of the response is not placed in the user-RH field of the SEND or SESSIONC RPL. Thus, the original setting of the RPL's user-RH field is preserved. This applies whether the POST=RESP is explicit, for example:
SEND POST=RESP,STYPE=REQ,CONTROL=DATA,RESPOND=(NEX,FME)
or implicit, for example:
SESSIONC STYPE=REQ,CONTROL=SDT
Refer to the description of the SEND and SESSIONC macroinstructions in Conventions and descriptions of VTAM macroinstructions and Synchronous versus asynchronous operations, in this chapter, for details about the POST operand.
