Description

The NAMESPACE() function returns the name of the currently active namespace, or an empty string if no namespace is active.

Namespaces are declared using the NAMESPACE command, creating a dynamic array which can be referenced by the namespace name. After declaration of a namespace, any PUBLIC variables declared are attached to that namespace, becoming members of the array. This allows the creation of multiple PUBLIC variables with the same name, provided each belongs to a separate namespace.

Issuing NAMESPACE without a <namespace name> deactivates any current namespace.

Example

procedure proc1
namespace namespace1
messagebox("Namespace is " + namespace())
public pub1 = "Public variable declared in proc1"
return
 
procedure proc2
namespace namespace2
messagebox("Namespace is " + namespace())
public pub1 = "Public variable declared in proc2"
return
 
proc1()
proc2()
display memory
? namespace1.pub1
? namespace2.pub1
namespace
messagebox("Namespace is " + namespace())
public pub1 = "Public variable, no namespace active"
? pub1
?

output
