          and other reply receive parameters.
        
            status.i2.v = NTRRPY( reqid.i2.r,[rpyadr.i2a.r],[maxlen.i2.r],
                                  [efn.i1.r],[astadr.f.r])
            status.i2.v = NET_RECEIVE_REPLY( reqid.i2.r,[rpyadr.i2a.r],
                                             [maxlen.i2.r],[efn.i1.r],
                                             [astadr.f.r])
        
         reqid    word containing the identification code of the request
                  whose reply receive parameters are to be changed.
        
         rpyadr   the new reply buffer.  If defaulted, the address of the
                  old reply buffer is retained as user must have specified
                  a buffer to receive replies.
        
         maxlen   word containing the new reply buffer size in words.
                  If defaulted, then the size of the reply buffer is
                  unchanged (the old size is retained).
        
         efn      a byte giving the number of an event flag to be set
                  when a reply is received.  If explicitly defaulted,
                  event flag 0 is used (on the VAX); implicit defaulting
                  (short argument list) leaves the event flag number
                  unchanged.
        
          astadr  address of user's reply AST routine.  If explicitly
                  defaulted, no user reply AST will be invoked; implicit
                  defaulting leaves the reply AST address unchanged.
        
         status   returns ACNET Global Status (sign-extended to 32-bits):
                      =0 for complete success
                      >0 for conditional success and pending
                      <0 for error condition
        
         The error codes returned are:
        
            -02 = local system out of space: insufficient dynamic memory
                  to declare network AST.
            -21 = not connected to network
            -22 = insufficient number of arguments
            -24 = no such request or not a request id.
            -25 = illegal event flag
            -46 = network error #1: AST quota exceeded while attempting
                  to declare network AST.
            -47 = network error #2: not owner of request block
            -48 = network error #3: request block is already locked for modify
