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 COMPATIBLE, 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 ?
output
Namespaces:
------------------------
NAMESPACE1 Dynamic array (refcnt 2)
.PUB1 Character 'Public variable declared in proc1'
NAMESPACE2 Dynamic array (refcnt 2)
.PUB1 Character 'Public variable declared in proc2'
Memory Variables:
------------------------
** Total of ** 4 variables defined and 298 bytes used.
Public variable declared in proc1
Public variable declared in proc2
Public variable, no namespace active
