More on Declaring Arrays
v Unless you do something special, the bounds of an
array in the declaration must be constants:
           Dim a(1 To 100) as Integer
v We can declare constants though for easier

    Const nRows As Integer = 30
    Const nCols As Integer = 30
    Dim newCells (1 To nRows, 1 To nCols) as Integer
