GDL Directives for Namespaces
GDL has directives that establish namespaces for objects that can be shared by multiple GDL source files.
GDL contains the following namespace directives:
*DefineInNameSpace specifies all definitions of sharable objects that belong to this namespace.
*UsingNameSpace defines a namespace context to search for object references without an explicit namespace qualifier.
For more information about namespace directives, see GDL Namespaces.
