You declare a variable to specify its name and characteristics. The declaration statement for variables is the Dim Statement. Its location and contents determine the variable's characteristics. For variable naming rules and considerations, see Declared Element Names.
Visual Basic recognizes the following five categories of variables: Numeric. String.
Declaration of a variable is for informing the compiler of the following information: name of the variable, type of value it holds, and the initial value if any it takes. i.e., declaration gives details about the properties of a variable. Whereas, Definition of a variable says where the variable gets stored.
The As keyword precedes the declaration of the variable type (String, Date, Integer etc). For a complete list of Visual Basic variable types see Understanding Visual Basic Variable & Constant Types.
The asterisk declares the variable as a fixed-length string, where the number indicates the length of the string:

The declaration of a fixed-length string variable contains an asterisk (*) to tell Visual Basic that the string will be a fixed length. The final parameter, strlength, tells the program the number of characters that the variable can contain.
They may be required for an API call, see this question:
VB6 - Is there any performance benefit gained by using fixed-width strings in VB6?
The only time in VB6 or earlier that I had to use fixed length strings was with working with API calls.
