done;

I'm a newbie aswellSmilie

Thanks for the reply but I actually solved the problem while messing around with itSmilie.

I wrote the following function:
Code:
function save_file()
{
printf ("\n%-35s%-35s%-35s", uwi, curve, FILENAME) > "new" FILENAME;
}

The variables I created are: uwi, curve
FILENAME is an AWK standard variable.

Hope this helps someone out there. If there's a better way to do this, please feel free to post it here, afterall, I'm a beginner. Otherwise, consider this problem solvedSmilie.
