((Variable)) which can be referred only within a certain range.
The range is called 'Scope'. The scope of ((Ruby)) is among:
* The entire program
* Class and module definition
* ((Method)) definition
* ((Block))
and only ((block|Block))
can access the local variable in the outside scope.
An effective range of the local variable is

to an end of the scope.
The effective range is fixed statically, and is unrelated
