The flows depicted in Figure 1 through Figure 1 indicate when the alias selection function is invoked and for what reason. The following information applies to the flows:

• Unless otherwise noted, the flows proceed as though the alias selection function does not return any translated names and that no host is running the NetView® alias application program.
• If the exit returns a translated name, subsequent hosts do not request translation for that name.
• If the DLU real network ID and real name are already known, either through prior translation or a predefined real CDRSC, VTAM® does not pass the DLU name to the exit for translation in a subsequent session.
• Associated LU names do not appear if the SLU is not using an associated LU table.
• All flows proceed as though the gateway control is SHARE/SHARE. If the gateway control is ONLY, alias invocations and RU flows vary slightly.
