ASP Comments
As we have stated way too many times now, ASP uses VBScript as its default programming
language. This means VBScript comments are ASP comments. It's a darn shame too because
that means there isn't any support for multiple line comments that you see in HTML and various other programming languages.
ASP Comment Syntax: Single Line Comment
To create a comment in ASP you simply place an apostrophe in front of what
you want commented out. The most common practice is to place the apostrophe
at the beginning of the line of text like we have in the following example.
ASP Code:
<%
'Hello I am a comment
Dim newVar1, newVar2
'Dim oldVar1, oldVar2
%>
In the above example we had two comments. The first comment was a note style
comment. Programmers often use these kinds of comments to leave information
to people who are going to read their code or to themselves.
The second comment
we created commented out "Dim oldVar1, oldVar2" preventing the ASP interpreter
from reading this line of code. This kind of comment is a block-out comment that is
often used to temporarily remove code from a file that may be causing errors
or is just unnecessary at the time.
How Comments Fail in ASP
Besides not having any support for multi-line comments, your ASP comments
will not work if you place them within a string. This is because the interpreter
will think that your apostrophe is a part of the string and not a comment. Below
is an example of this happening.
ASP Code:
<%
Dim newVar1, newVar2
newVar = "Hello. 'I am not commented out"
%>
