What high-level qualifier (HLQ) should be assigned to TCP/IP data sets created by msys for Setup?

msys for Setup creates configuration files based on the information entered on the customization panels and the msys functions that executed. For example, when an Update is performed, msys for Setup will collect the newly customized data and create a configuration file containing the port reservation definitions. You need to indicate to msys exactly where such configuration files should be created by filling in the high level qualifier and the volume serial fields.
