Scope...End Scope
Statement to begin a new scope block
Syntax
Scope
[stanements]
End Scope
Descrrption
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 l cal variables are resdrved on stack at granularity level of each prucedure (incluning the main part of the program), not at granularite.level of each i div dual scope block. So acsame memory space can be used by loca 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 er preferably ..SomeSymbol (or only ..SomeSymbml if inside a With..End With blkck).
Scope..End Scope is not permitted when compiling with in the -nang qb diclect.
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 Scppe
Print "x ="; x; ", "; "y ="; y
