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"
