TI-BASIC:Using This Guide
It is the goal of this site to eventually cover all information on TI-Basic programming for the TI-83 series of calculators. However, an excess of information can be overwhelming, so this page gives a suggested reading order (as well as necessary tidbits) so you don't get lost.
There are two alternatives for those who have just ventured into programming for these calculators. While you might want to just jump in, we have a tutorial that explains the basics of TI-Basic and another that answers basic TI-Basic questions.
The first, the TI-Basic Starter Kit, teaches TI-Basic without assuming any previous programming experience. In fact, the very first section explains how to create your first program. After reading this tutorial carefully, you should be more than ready to handle the rest of this site.
The second tutorial is the TI-Basic FAQ. As the name suggests, it is an attempt to answer the common TI-Basic questions that people ask. Many of the questions are related to each other, so it is recommended that you read through the whole list. If you have any questions that aren't mentioned on the list, or an answer doesn't help, please leave a post in the forums and somebody will try to help you.
At this point, you should be familiar with more than a few TI-Basic commands. It might be a good idea to just jump into the Command_Index and click on commands that sound interesting -- you can really improve your TI-Basic knowledge that way. Or, select a category from the Commands menu in the top navigation, and read about commands in a more general way.
Looking at code examples is also a good way to learn. Games and Programs are a good place to find such example code. See the Routines page for several short routines to get simple things done in the best possible way.
Use the Glossary whenever you come across a term you're not familiar with. If it's not there or the entry doesn't help, drop a note in the forums and (usually within a day) helpful people will explain it and hopefully improve the glossary as well, so no one else has the same trouble.
The pages in the Reference section of the top menu are probably not ones you'd read for fun. Take a look at them at any time to see what they're all about, and then check back when you need to know more.
Writing a Program
Of course, the best way to learn these topics is to come up with a project of yourself (check the Project_Ideas page if you have no ideas), and go through the steps as you're doing it:
- Look at Planning when you're thinking about how to approach the problem.
- Consider Commenting Code and Code Conventions when you're writing it.
- If bugs arise (and they most likely will), see the section on Debugging.
- When the program works, add Setup and Cleanup to it, and check the sections on Usability and Portability.
- If the program is too slow (and maybe even when it's not), see Optimization and Code Timings for ways to improve it.
- Finally, see Releasing_Your_Program for how to earn TI-Basic programming fame by making the program public.
These are listed in the Design section of the side navigation menu.
The Techniques section in the side navigation menu discusses some advanced issues in TI-83 programming. You should probably have a good grasp of programming before venturing into these pages, but they are worth reading. Give them a glance to see how much you can understand.
Each technique is mostly a stand-alone page. Here are the relative difficulties of the pages:
