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.
