TI-BASIC is the unofficial name of a BASIC-like language built into Texas Instruments (TI)'s graphing calculators, including the TI-83 series, TI-84 Plus series, TI-89 series, TI-92 series (including Voyage 200), TI-73, and TI-Nspire. TI does not officially name the language, but only refers to it as "extensive programming capability". Though the TI-BASIC name has stuck, the syntax is different from almost all standard BASIC implementations, sometimes resembling other languages such as PILOT or even Forth.

NOTE: this is distinct from TI BASIC, which was used on the TI 99/4A home computer.

1982–1983

Learned on the TI-99/4A computer - not sure if it is the same variant as now on the graphing calcs

1987

Drink three liters of jolt, down a jumbo bag of cool ranch chips, code yet another game on Gabe's TI-99/4A, wait for one of us to get too slaphappy on caffeine and start munging the keyboard until it reboots, game unsaved.

1993–1995

1994–1997

1995–

1996–1998

This is what really got me started programming: graphing calculators. Learn math class technique once, program calculator to do it for me, spend rest of class writing text adventures. <3

1996–2000

A wonderful time-saving feature for all those forumlas that weren't built-in...

1996–2000

Wrote what I consider my first "real" programs on this platform. My favourite was a blackjack game. Two character variable names and forced use of the GOTO statement were interesting aspects. My TI-83 was stolen in the summer of 2000.

1996–2000

I don't think I ever used TI-BASIC outside of high school when I programmed on both a TI-82 and later a TI-89.

1996–1999

My first real experience with programming. There was a small group of kids at school that started writing all sorts of programs for the TI-83. Games and cheat programs galore. Still proud of some of the games I wrote.

1996–2003

1997–2008

1999–

2000–2003

Wrote a quadratic equation solver because I couldn't memorize the damn formula. Then sold copies to the students who were actually just bad at math.

2000–2005

2000–2003

Wrote a quadratic equation solver because I couldn't memorize the damn formula. Then sold copies to the students who were actually just bad at math.

2001–2008

2002–2005

I stubbornly learned Calculus aided by the same scientific calculator I was given in 5th grade, but learned enough to prank high school friends and aid some college homework crunching.

2003–

Used to write a whole host of programs while bored in class. Including craps, quadratic solver, heron's solver.

2005–2007

First language I ever really learned (minimal amounts of C# in grade 9 don't count). Good fun in math class. :)

2005–2007

2007–

Use it almost exclusively when bored in class. Usually spent my time writing programs to solve mathematical problems in order to increase productivity. Anything else I wrote was some sort of game for playing with friends.

Truly my first programming language, though I didn't really understand that I was programming. I just made the computer print out things I told it to print out. I also seem to remember getting it to draw simple pictures.
This was the first (and only) computer my family owned up until age 11.
