Code Problem: How to Write this into a VBA code

I have recorded the below macro. However, I want to know how to write it as code. I have read on how to write a macro, but I can't grasp it. So, I thought that since I know how this macro works, that if someone can help me write it, it would make more since to me.

I want to write it because when recording it records Range("B5:B100").Select and it want always be that range.

    sheets("DATA DUMP").Select
    Range("B2").Select
    Range(Selection, Selection.End(xlDown)).Select
    Application.CutCopyMode = False
    Selection.Copy
    Sheets("DOT 9A_DUMP").Select
    Range("A5").Select
    Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    Range("B4:L4").Select
    Application.CutCopyMode = False
    Selection.Copy
    Range("A5").Select
    Selection.End(xlDown).Select
    Range("B5:B100").Select
    Range("B100").Activate
    Selection.PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone, _
        SkipBlanks:=False, Transpose:=False
    Range("A5:F5").Select
    Range(Selection, Selection.End(xlDown)).Select
    Application.CutCopyMode = False
    Selection.Copy
    ActiveWindow.SmallScroll Down:=-114
    Range("A5").Select
    Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    Range("A5").Select
End Sub
