TI-83/84/+/SE TI-Basic Routines List

[spandiv]

Over the course of the last few months, I have noticed several new topics started by people asking for code help, even though there already exists one or more previous topics that provide the relevant help. All somebody has to do to find them is just use the forum search engine, but it seems like most people ask questions first and search second. Unfortunately, this pattern of behavior not only results in redundant topics, but it wastes people's time and energy.

I realize that it is simply futile to try to get people to use the forum search engine before starting a new topic because you are working against human nature, so I decided to take a different approach. I went through all the TI-Basic topics myself, and organized the topics/posts with code into categories for easy searching. Now, if you don't feel like using the forum search engine, please at least use this routines list! Thank you.

Hey, all of the above links are dead.

[calcdude84se]

You just need to add "forum/" (w/o the quotation marks) after "unitedti.org/" so the address now reads unitedti.org/forum/index...

[SirCmpwn]

Oh okay. Maybe an admin should fix that.
