Denoting a Variable’s Data Type

Table 3-1 lists the prefixes you can use to denote a variable’s data type.

If you’re unsure of what prefix to use, use obj. For instance, when automating Microsoft Word, you might create an instance of Word’s Application object. Because no prefix has been designated specifically for Word objects, obj works just fine, as shown in the following statement:

						Dim objWord As Word.Application
