Either delete line 82 or put a # sign in the first column to ignore the line altogether.

The purpose of this paper is to provide you background on SQL Server. Itâ€™s your self-study guide for learning fundamentals. It includes both the history of SQL and its technical basics. Concepts and definitions will form the solid foundation of your future DBA expertise.

Then you need to rewrite where the line is output. I get it, the example you have shown us does not add or subtract, it compares and gives the answer. You do not need the line "The Answer Is:" in this case but in other cases you do.

You could do this in a number of ways... Put the answer statement within the case section that needs it. This will require many duplicate line. Better way would be to place the lines in a subroutine that is called from with the case statements. I am certain I could come up with more...

Thanks technoweeb could you give an example on how id put the answere statement within the case section for each area? iv been trying but keep getting syntax errros

I Think its working =)

Easiest way is to use a function so as to not repeat code.

Here's an example that shows how to use a function. As a bonus, I've fixed your spelling errors, corrected your indentation and fixed your factorial code.

So I am just curious... The last comment by the OP is that it was working.

The comment after that was from Tintin who did what I suggested and rewrote the script using a function (I said subroutine, basically accomplishing the same outcome). He also contributed to the script with some clean ups as well.

I have been a member here for a very long time and it seems that answering or completing homework assignments has always been frowned upon by EE Staff and Community. This question, as well as at least one previous question from the OP appear as homework assignments. I chose to not challenge that fact for this question but give a push in the right direction so the OP can learn what it is they obviously want to learn. I do not find that learning is accomplished by someone just doing the work for me. I also do not know for 100% certainty that this was a homework assignment. I could have just as easily re-written the assignment and sent the OP on his way, but this is not truly in the spirit of the EE site.
