  2. Personal Macro Workbook • A workbook that opens automatically whenever Excel is opened • Any macro stored in this workbook can be used by any open workbook

  3. Macro • Macro storing Excel commands (written in Visual Basic for Applications) • Visual Basic Editor (VBE) creating, displaying, running, and debugging macro commands • Project Explorer locating macro modules • Code window displaying micro statements

  8. Relative Cell Reference (2) • Range: dimensions of cell(s) • Range(“A1”): a single cell • Range(“A1:A3”): a range three rows by one column • Syntax: ActiveCell.Offset(2,1).Range(“A1”). Select • Always selecting a single cell two rows below and one column to the right of the active cell

  9. Data Management Macro • Automating data list management tasks • Prompting user for input to populate a criteria range • Filtering list or displaying database functions based on those criteria • Use range name for the list or the criteria range

  10. Visual Basic for Applications • Tool menu, Macro, Visual Basic Editor • Or Alt+F11 • VBA: a subset of Visual Basic • Macro converted to VBA programs • Creating macro using macro recorder • Using Visual Basic Editor to modify
