Blogger used to irritate me when I have to type any code snippet in courier font.But this is only until Susam Pal suggested the use of <pre></pre> tag.

Thanks Susam for this knowledge.Susam also has his blog .If you are a Math buff, his blog is one of the good one to subscribe.

PS:- While I am typing this I forgot about & l t ; and & g t ; for but am able to recollect and use here :))
