That's too simple, but kinda reduntant, they are actually 4 loops
inside one-another, can't think of creating 4 files each containing an
integer, this won't be programming, its carpenting.

did not get this one, you mean ;

i= $(cat name_of_the_file)   ???

if that's what you mean, then you solved my problem.

Ya, That's aa coooool thing to learn, I have seen what perl scripts can
do.  But I think its very extensible language, I mean I'll be 65 years
before I reach the bottom of it, is that so, I'm ready to learn new
things, and always wish to learn the devls such as perl, tcl, tk, but
I'm kinda afraid that they'd be difficult for me to learn.

Thanks very much for your replies, see ya soon.
