Any reference material related to above topic would have been really helpful.

Why don't you tell us more about your specific application. At the moment it just looks you're writing a paper and you want us to do your research for you.

These are questions from the online CLAD example, and people have probably asked about it before. Do a search for "CLAD questions" or for the text of the question itself.

My answer to #2 would be "none of the above". Good thing I've never taken the CLAD.

Still curious why one would need reference material...

OP probably just wants some background reading, instead of just an answer.

Very well could be! But mentioning that up front would have been nice. Especially since he/she is a first time poster.

Going back to work now...

I know NI's answer to #2. My answer would have been a CSV file. It's readable by anything, Excel included. And has the benefit that the character that is separating your data is obvious in any text reader. But that's just me...

While we love to help here, we get a fair share of posts from people who don't want to learn, but just want us to do their school project for them. Sorry if I misunderstood your intent.

We use CSV files a ton (too much) here too, but be warned: CSVs don't like Europe (or Europe doesn't like CSVs) - any country that uses commas as a decimal separator can't use commas as a column separator. After being bitten by this years ago all my text logging code allows for a re-configurable separator and file extension.

I have wrote the CLAD n waiting for results...If i fail ill come up with more qun's :)...Adios
