3. Use code tags around code.
Posting code without them makes your code hard to read and difficult to be copied for testing.
Select your code and click the [#] button at the top of the post window
(if you are editing an existing post, press Go Advanced to see the [#] button).
The result will appear like this in the post window:


[code]
your code here ...
and here ...
and here
[/code]

... and appear like this when posted:

your code here ...
and here ...
and here
You can also type the code tags in manually if you prefer
