Is that the 'christ' part of your nick getting some play, Tom? :)
I think that sending the OP off to learn 'tbl' and all that other related stuff would drive him bats. He's having a hard enough time understanding how to use code tags, for Ghu's sake. I suspect 'printf' would be a bit more his speed - if he ever settles down and actually pays attention to the people's replies to his questions.
Deepak - please start paying attention to the replies that people have given. There's plenty of information here, all you would ever need to do what you've asked about. And PLEASE start using code tags: when you write your post, surround the code part - the part that you want to show in its original format - with a <c> tag above it and a </c> tag below it. Everyone, including you, will be happier if you do.
