Scope...End Scope

Statement to begin a new scope block

Syntax
   Scope
      [statements]
   End Scope

Description
   The Scope block allows variables to be (re)defined and used locally in a 
   program.

   When a variable is (re)defined with Dim within a scope structure, this 
   local working variable can be used from its (re)definition until the end 
   of the scope.  During this time, any variables outside the scope that 
   have the same name will be ignored, and will not be accessible by that 
   name. Any statements in the Scope block before the variable is redefined 
   will use the variable as defined outside the Scope.

   The local variables are reserved on stack at granularity level of each 
   procedure (including the main part of the program), not at granularity 
   level of each individual scope block. So a same memory space can be used 
   by local variables belonging to different scope blocks.

   To access duplicated symbols defined as global outside the scope block, 
   add one or preferably two dot(s) as prefix: .SomeSymbol or preferably ..
   SomeSymbol (or only ..SomeSymbol if inside a With..End With block).

   Scope..End Scope is not permitted when compiling with in the -lang qb 
   dialect.

Example
   Dim As Integer x = 5, y = 2
   Print "x ="; x; ", "; "y ="; y
   Scope
      Dim x As Integer = 3
      Print "x ="; x; ", "; "y ="; y
      Scope
         Dim y As Integer = 4
         Print "x ="; x; ", "; "y ="; y
      End Scope
   End Scope
   Print "x ="; x; ", "; "y ="; y

Dialect Differences
   * Explicit Scope..End Scope blocks are available only in the -lang fb 
     and -lang deprecated dialects.
   * Explicit Scope..End Scope blocks are not available in the -lang fblite
     and -lang qb dialects.

Differences from QB
   * New to FreeBASIC
