What is Useful Programs?
Useful Programs is a calculator site which includes useful programs for TI-83 Plus and TI-83 Plus Silver Edition calculators. The aim of this site is to show that the calculators are not only for games and if basic programs are programmed well, they are not trash.

What kind of programs do you have on this site?
All the programs here are created on a TI-83 Plus calc with TI-Basic language. However, these programs are not basic programs that require too much space. All of the programs here are less than 5kb (except Biorhythm Calculator) and they are made up of only one file. You don't need to worry about any pictures, lists, strings or groups.
Generally, the programs are not as slow as many other basic programs. However, due to the nature of Basic language, some parts of the programs may run slow.

I loved your programs, what can I do for you in return?
You can support Useful Programs by clicking on the Amazon.com links around the site and then shopping from there. You can purchase anything, not just calculator stuff, but clicking doesn't support Useful Programs. You must purchase things.
You don't need to pay anything extra, consider Useful Programs as a passageway to Amazon.com.

Who is in charge here?
All of the programs on this site and the site itself is created by Burak Gul, myself, also known as Eniyi on some message boards.
I know the design of the site sucks, but I'm not a creative person. Even my deep knowledge of Microsoft FrontPage and Adobe Photoshop can't help me. I hope that this design is at least easy to navigate.
For this reason, I appreciate any help, comments and suggestions on this site.

How can I contact you then?
You can use the Contact Me page for a contact form, or for my email address or to see my ICQ status or you can use the message board.
