Variables in ASP Declaring variables in ASP is simple, especially since all variables are of type Variant. You don't have to define the variable's type (such as if it's an integer, string, etc.). Rather, you just declare the variable using the Dim keyword and it has the potential to be anything. Here is some code creating and assigning values to a few values: <%@ LANGUAGE="VBSCRIPT" %> <%     'Declare a variable. A single tick denotes     'a comment in VBScript     Dim MyName     'To declare a variable, you just put the word     'Dim in front of the variable name.     'Let's assign something to MyName     MyName = "Scott Mitchell"     'Let's create some more variables     Dim Age, Pi     Age = 20     Pi = 3.14159     'Since all variables are variants, we can     'Reassign values. (Bad coding, though!)     MyName = 45     Pi = Age     Age = "Yellow Schoolbus!" %> If you wanted to print out the variables, you could simply do a Response.Write. Here is an example: <%@ LANGUAGE="VBSCRIPT" %> <%     'Declare a variable. A single tick denotes     'a comment in VBScript     Dim MyName    MyName = "Scott Mitchell"     'Print out MyName     Response.Write(MyName)     'To concatonate strings in VBScript, use the     'amperstand     Response.Write("My name is " & MyName) %> Since variables are Variant, you may be wondering how you can tell what, exactly, is in them. There are some built-in functions which help you in this task. <%@ LANGUAGE="VBSCRIPT" %> <%     'Declare the variable MyName.     Dim MyName     MyName = "Scott Mitchell"     'Will print out false     Response.Write(IsNumeric(MyName))     'Will print out false     Response.Write(IsDate(MyName)) %> You can explicitly cast the type of a variable when you assign to it. It is good programming technique to do that! That is because if you have a variable SomeString with the value "5" in it, and you want to assign it to a variable SomeInt, you don't want SomeInt to be a string but an integer. So you could type: SomeInt = CInt(SomeString). Here is an example: <%@ LANGUAGE="VBSCRIPT" %> <%     'Declare the variable MyName.     Dim MyName     'Explicitly make Myname a string     MyName = CStr("Scott Mitchell")     Dim Age, Pi     'Explicitly make MyAge an integer     Age = CInt(20)     'Explicitly make Pi a double (a floating point     'value with double preceision)     Pi = CDbl(3.14159) %>
