Agreed. Which is why he does not get any fish before showing his
attempts at fishing for himself ;-)

Why do you all just assume it's a homework assignment? Could it not just
as well be a simplified work project? I would not be at all surprised if
this was something handed down by one's boss or project manager, and
written in a simplified form (which is what one *should* do, no?) I
really see little point to make such an assumption, and I'm sure no one
likes being talked down to.

gack, you again? having done a bit of perl, written requirements and
assigned tasks, i would have never said 'must use a subroutine'. that
plus the wording of the other requirements reeks of homework. but you
again seem to take offense at what is patently obvious to all the others
here. why don't you stop doing that and actually either answer his
homework assignment by giving him a fish or stfu. did you even notice
that the assignment is really a simple form of more/less written in
perl? how could that be a real world project assignment? your comment
insults the theoretical project manager by saying he would rewrite
more/less in perl for no reason. how dare you insult him? what gives you
the right to decide he is a poor project manager? maybe he doesn't know
about more/less? maybe he needs a version in perl for some unknown
reason you can't comprehend? i prefer to take the easier assumption
(occam's razor and all) that is is a homework assignment.

now go sit in the corner of the classroom facing the walls!

It could be homework, just as it could be any number of things. Could
just be how the OP put together his post, listing what he wanted to do.
The point is _you_ _don't_ _know_.

and you know it is the opposite? how nice of you to tell us. we will
consult with you before we decide if other posts are homework. will you
be available 24x7 for this job? we all appreciate your doing this
thankless job and for no pay! do you want a long term contract to be the
homework monitor? for no extra pay will you actually answer perl
questions? or will you just make sure we do the right thing and you just
take the glory? please guide us O enlightened one as we need your help!

and there was no sarcasm in that, sincerely!
