Comments are used to make your code more readable and documented? In ASP an apostrophe (single quote) is used to comment a line of code.

Here is the example

<%

'Variable declaration
DIM username, age, country

'Getting values from HTML form
username = Request.Form("username")
userage = Request.Form("userage")
usercountry = Request.Form("usercountry")

'Writing values of the html form
Response.Write("User Name = " & username & "<br>")
Response.Write("User Age = " & userage & "<br>")
Response.Write("User Country = " & usercountry & "<br>")

%>

Comments do NOT get interpreted so you can put whatever you want into them. However, comments are important to keep track of what you are doing in the code.
