In fact, how to say, the statement is wrong

B4X:

Dim x as Int
Select x   <<<----
  Case 0
   '
  Case 1
End Select

is there any programming language that can catch an undeclared variable?

how can a program do something with a variable that is unknown? it could be a string, it could be a integer, a map, a list, a view,... so why should it work?

sample how it should look:

B4X:

Sub catch_me(x As Int)
    Dim l As List
    l.Initialize

    Select x
        Case 0
            Dim new_x As Int = x*25
            l.Add(new_x)
        Case 1
            Dim new_x As Int = x/8
            l.Add(new_x*2)
        Case Else
            l.Clear   
    End Select

    'do here something with l
End Sub

    Dim x As Int
  
    Select x
        Case 0
            l.Initialize          
    End Select

B4A can catch some of it. The following sample below will show "Undeclared Variable" for "l.initialize" in the log.

or do you mean the right top logs just to inform you that there is an error before a compile?

Yes, the Top Right Log.

My first post codes will compile successfully and cause an error when case 1 is triggered.
