Advanced Scoping and Namespaces
Predefined Scopes
JMP provides predefined that cannot be removed or replaced. Each of these scopes has specific roles,
depending on its associated object.

Description
Global names are shared throughout the JMP environment.
Scope of the executing script.
JMP built-in functions. For example, Builtin:Sqrt(). These names are shared
throughout the JMP environment.
If you over-ride a JSL function with a custom function, you can still access the
built-in JSL function by using this scope.
Nearest local scope. Can be nested within the user-defined functions, Local and
Parameter.
Provides a namespace block inside Names Default to Here(1). Local(
{Default Local}, ) does not always work due to the lifetime of the local block,
but Local Here() is persistent across the call.
Scope of the containing user-defined window. (Rare.)
Scope of the current platform. (Rare.)
Scope of the containing context box. A context box is nested within a user-defined
window. (Rare.)
Example of Using the Window Scope
This example uses the Window scope to pass information during execution. Explicitly scoping the variables
x and y to this window ensures that JMP does not try to scope x and y in other contexts, such as a data
table. The variables x and y are created and used solely inside the Window environment. The Window scope
is similar to using Local(), but more useful because Local() is limited in the places that it can be used.
New Window( "Example",
window:gx = 20;
window:gy = 50;
Graph Box(
Frame Size( 200, 200 ),
Handle(
window:gx,
window:gy,
Function( {x, y},
window:gx = x;
window:gy = y;
