Type declarations 13/14
Session Links
  • You get better performance and some error detection if you declare data types:
    • Arguments
    • Return values
    • Variables
  • Variable Types
    • Variant (the default)
    • Integer (<32k)
    • Long (>32k)
    • Double (floating point)
    • Boolean (true, false)
    • Object (Excel entity such as a range)
    • String (text)
    • Others: see on-line help

Before we fill in the argument list, let’s learn about type declarations. Different kinds of data are represented in your computer using different amounts of memory. Type declarations tell the compiler how much space to allocate for each data item. For example, integers usually take less space than doubles, or Objects.

If you don’t declare a type, Excel assumes the worst and allocates lots of space. The undeclared type is called Variant. You get better performance if you declare types.

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?
