NAMESPACE

Purpose

Declare a namespace to which all public memory variable will be attached while the namespace is active

Syntax

NAMESPACE [<namespace name>]

See Also

ARRAY(), DECLARE, DIMENSION, LOCAL, NAMESPACE(), PARAMETERS, PRIVATE, PUBLIC, SET STRICT, STORE

Description

The NAMESPACE command declares a namespace and creates 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.

The currently active namespace can be determined using the NAMESPACE() function.

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
?
