the system which supports the specified logical trunk and node.
            status.i2.v = NTGTNM( [lognod.i2.r],[taskid.i1.r],tsknam.i4.r )
            status.i2.v = NET_GET_TASKNAME( [lognod.i2.r],[taskid.i1.r],

         lognod   word giving the destination logical trunk and node.
                  If defaulted, the local default logical node is assumed.
         taskid   a byte giving the logical task id of the network task
                  whose name is to be returned. If defaulted, zero is
                  used and the network task name of ACNET is returned.
         tsknam   longword in which the network task name is returned.
         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:
            -01 = Retryable I/O error
            -02 = local system out of space: no free buffers, no free
                  control blocks, or request table full.
            -03 = Insufficient memory at destination
            -21 = Not connected to network
            -22 = Insufficient number of arguments
            -30 = No such logical node
            -33 = No such destination task
            -41 = Hard I/O error
            -42 = Node down or offline
            -43 = System service error: no network process.
            -44 = nontranslatable error: XSC block does not exist
            -45 = Internal network error
            -48 = network error #3: control block or buffer vector in use
