chetan,
if you have to look into overridding perl's print function, you should
probably look into radically changing the structure of your program, imho.
if nothing else, build up the output you want to create and store it in a
scalar, then print that when you know it's ok. better still, look into a
templating system (pls see threads from the last several days covering
this topic extensively) to divorce the output format from the logic of the
script.
