Global Structure • The specified directory on your local system, if you do not specify a system name in the reference. If you omit the system name from an implied namespace reference, you must supply a double caret (^^) within the directory reference to indicate the omitted system name. To specify an implied namespace on a remote system: ["dir","sys"] To specify an implied namespace on the local system: ["^^dir"] For example, to access the global ORDER in the BUSINESS directory on a machine called SALES: SET x = ^["BUSINESS","SALES"]ORDER To access the global ORDER in the BUSINESS directory on your local machine: SET x = ^["^^BUSINESS"]ORDER To access the global ORDER in the defined namespace MARKETING: SET x = ^["MARKETING"]ORDER 2.3.2.2 Environment Syntax The environment syntax is defined as: ^|"env"|global "env" can have one of four formats: • The null string ("") — The current namespace on the local system. • "namespace" — A defined namespace that global is not currently mapped to. Namespace names are case-insensitive. • "^^dir" — An implied namespace whose default directory is the specified directory on your local system. • "^system^dir" — An implied namespace whose default directory is the specified directory on the specified remote system. To access the global ORDER in your current namespace on your current system, when no mapping has been defined for ORDER, use the following syntax: 12 Using Caché Multi-Dimensional Storage
Referencing Globals SET x = ^|""|ORDER This is the same as the simple global reference: SET x = ^ORDER To access the global ORDER mapped to the defined namespace MARKETING: SET x = ^|"MARKETING"|ORDER You can use an implied namespace to access the global ORDER in the directory BUSINESS on your local system: SET x = ^|"^^BUSINESS"|ORDER You can use an implied namespace to access the global ORDER in the directory BUSINESS on a remote system named SALES: SET x = ^|"^SALES^BUSINESS"|ORDER Using Caché Multi-Dimensional Storage 13
