SDISC Assembler Call - NetEx

SCONF FORTRAN CallThe SCONF (confirm) call provides a means for an offering program to confirm (to the connector) that theconnection has been successfully completed. A negative response to an SCONN would be an SDISC. Beforeissuing the SCONF call, an SOFFR must have completed successfully by receiving an SCONN response.The calling program must provide a NRB with an NRBNREF relating to this session.Call Operation ParametersCALL SCONF[W] (nrb, buffer, length, datamd)The following parameters were shown in the SCONF call format. The parameters must be specified in theorder presented. If parameters are omitted, the commas must still be used.CALLThis is a required standard high level call instruction.SCONFThis is the verb for this call. Either SCONF or SCONFW must be specified. SCONFW specifies thatthe calling program must wait for the call to complete before processing is resumed.nrbThis required parameter is the address of the NRB data area that is to be passed to NETEX.bufferThis optional parameter specifies the start of an array that holds the user data that is to be sent to thecorresponding application.lengthThis optional parameter specifies the length of the data (in addressable units – Unisys words) that isto be sent to the corresponding application, to be presented with the completion of the correspondingapplication’s SREAD request. If no data needs to be sent to the other application, the length may beset to zero. The data type of length should be INTEGER.datamdThis optional parameter specifies the datamode to be used to send the connect data to the correspondingapplication. The data type of datamd should be INTEGER. Refer to NRBDMODE in“NETEX Request Block” for a discussion of the datamode parameter.SCONF Entry ParametersThe following NRB fields are used by SCONF on entry:NRBBUFA Address of outgoing Pdata (move mode).NRBLENLength of outgoing Pdata.NRBUBITPdata unused bit count.NRBDMODE Datamode of Pdata.NRBPROTA Address of outgoing Odata.NRBPROTL Length of outgoing Odata.SCONF ResultsThe following NRB fields are updated when SCONF completes:NRBSTATSuccess/failure code.MAN-REF-H307IP-04 FORTRAN Interface Page 53
