hi guys,
thanks for the awesome n fast response.
unfortunately you're right as rain as there is no tests too. so most of the stuff if we're lucky we stumbled upon some useful code or we check with the senior. and there's only one person there left who long enough to know at least some of the codes..i'll try out the method to see which is more useful. my end in mind is to have a clear listing of all the functions and what they do to prevent further code rot and redundant work.
~ thanks
