What are macros? 13/2
Session Links
  • Macros are small programs you write to add capability to Excel
  • There are two macro languages in Excel:
    • Excel 4 Macro Language (XLM)
    • Visual Basic for Applications (VBA)
  • Why two?
    • VBA was introduced in Excel 5.0; XLM was the only language before that
    • Microsoft wants to discontinue XLM
    • Customers have heavy investments in XLM
    • Both are provided for the time being
  • Which to use?
    • XLM is easier to learn and write
    • Documentation and help for XLM aren’t available in Excel 97 or later
    • XLM documentation is available at Microsoft.com
    • VBA is faster and more powerful, and it’s documented within Excel

All this talk about XLM is useful only because you might run into it someday. Or perhaps you already have. It is a macro language framework that was the standard prior to Excel 5.0. Macros written in XLM are still running in many companies, and Excel still supports them. But new macros are rarely written in XLM. Even companies with large investments in XLM code bases ought to be rewriting them — not because XLM is inferior to VBA, but because XLM expertise is relatively scarce and will only get more scarce as time passes.

This scarcity does present an opportunity for some. If you have XLM expertise or if you can acquire it, and if you know VBA too, you can probably provide conversion services to companies that are interested in converting their XLM code bases to VBA.

By the way, for Windows versions, Microsoft is getting ready to replace VBA with Visual Studio Tools for Office. They’ll continue to support VBA for a few years (possibly indefinitely, like XLM) but the future is VSTO. This means that before long, companies will need to convert both XLM and VBA to VSTO. On the Mac side, VSTO is problematic. We haven’t heard that it will ever be offered.

Function Macros

We focus on function macros in this course because they’re more likely than command macros to make a real difference in your facility with constructing models. For instance, when your customer wants to see result streams displayed as [Month1, Month2, Month3, Q1 Total, Month4, Month5, Month6, Q2 Total, …], you probably realize that such a layout makes copy/paste and fill very inconvenient. A macro can provide a simple means of producing the preferred layout from a more easily maintained pure month structure. It’s also easy to construct macros for running sums and running differences. Can you think of other applications for function macros that make your models easier to build and maintain?
