Variable lifetime
|
||||
-----------------
|
||||
|
||||
When setting a new variable, the variable is readable and writable in the
|
||||
node where it is created, and in the child nodes.
|
||||
If a child node write a variable defined in a parent node, the new value of
|
||||
the variable will be available in the parent node.
|
||||
When creating/setting/editing a variable or its value, the changes are
|
||||
available everywhere in the source code.
|
||||
|
||||
About the names
