Может ли код не работать, если в нем неверное объявление переменных, не закрыты циклы и т.д.? - VB

Dim A(1 To 5, 1 To 3) As Integer
Dim j, b, max, ind As Integer
Private Sub Command1_Click()
        Dim A(1 To 5, 1 To 3) As Integer
        Dim j, b, max, ind As Integer
        Randomize()
        For i = 1 To 5
            For j = 1 To 3
                A(i, j) = Int(Rnd() * 100)
            Next j
        Next i
        Print(TAB(10))
        Print()
        For j = 1 To 3
            Print(TAB(10))
            For i = 1 To 5
                ind = i
                max = A(i, 2)
                For b = i + 1 To 5
                    If max > A(b, 2) Then
                        max = A(b, 2)
                        ind = b
                    End If
                Next b
                A(b, 2) = A(i, 2)
                A(i, 2) = max
            Next i
