System and Other Functions$ZUTIL(69,20)Transfers global nodes with null subscripts with DSM-DDP.$ZUTIL(69,20,n)$ZU(69,20,n)ParametersnThe boolean value that specifies whether the network allows null subscripts.DescriptionWith Open M [DSM]-DDP networking, you can transfer global nodes that include null subscripts.$ZUTIL(69,20) controls this ability system-wide.When enabled (n=1), Caché can read and write global data with null subscripts across a networkconnection. When disabled (n=0), all data with null subscripts is effectively invisible,and all references to such data generate errors. The default is disabled (0).This setting only applies to DCP networks. On ECP, null subscripts are always allowed overthe network.Invoking $ZUTIL(69,20) without specifying n returns the current switch setting.Setting $ZUTIL(69,20) overrides the default system-wide; it does not change the systemconfiguration setting. This configuration default cannot be changed using the System ManagementPortal.ParametersnThe switch that controls whether Caché can transfer null-subscripted global nodes throughOpen M [DSM]-DDP. 0 = Disables system-wide transfer of null-subscript nodes. 1 = Enablessystem-wide transfer of null-subscripted nodes.By default, the ability to transfer null-subscripted globals is disabled. You cannot control thisswitch on a process level.For further details on subscripted globals, see Global Structure in Using Caché Multi-Dimensional Storage.654 Caché ObjectScript Reference
