I did it!

[Joel]

I wrote a decent, working program that actually does something semi-usefull!!!
Check it out! You can find the area of a circle with it!

I wrote a decent, working program that actually does something semi-usefull (areaformula.pl)!!!
Check it out! You can find the area of a circle with it! Also, can someone tell me what I did wrong with modifiedarea.pl and what the error (Main::useless used only once possible typo at...)means?

Thanks

Congratulations on your first program.

You should get in the habit of putting
use strict;
use warnings;

at the top of you code.
The first will make sure your variable names are accurate and the scope
is correct. Very useful. The second will save you a lot of work when it
comes to debugging bad code.

Great! Welcome to the programmer's world.

A couple tips:

The name you used for the zip file was better than the one
you used for the script. One told the user what what they
could expect from the program in clear language, the other
was cryptic and technical, relevant only to the writer of
the program. It's an important distinction to make early
on. A programmer's task is to make the technical available
in a logical format accessible to the non-technical mind.

Please do not use HTML mail when posting to newsgroups. It
really makes it difficult to respond to yoour posts. You
should be able to turn it off through the preferences or
options interface of your mailer.
