This sort of conversation has made many head-level dents in my wall before. "I need array arrays!" "What are you doing?" "I need array arrays!" "But why do you need your data arranged that way? For what purpose are you dumping all this stuff into memory?" "I need array arrays!" "...right."

I don't truly understand your question yet. You haven't given us a good enough sample of input and output for us to work with. But I suspect it may be entirely possible to get what you want in a multitude of ways, some with multidimensional arrays, some without them...

Hi Corona,

Thanks i understood , loading n number of variable with n number of data in memory is not good approach for just basically accomplishing HTML report, This is Just for my self knowledge/ interest i just posted.

I will implement the awk RS approach that could you be fine, This is Nice and learnt something from this Post.

If anyone didnt get my query will change the way i will post going forward so that will be clear to answer my queries.

Thanks All for your Valuable inputs on my requirement.

Thanks,
Regards,
karthikram
