1337

1337 (pronounced as leet) is primarily an Internet fad of writing words by replacing the standard letters with their alphanumeric counterparts. Within the TI community, this phrase is used to indicate that somebody is an advanced programmer and very knowledgeable.

68K

Motorola 68000 is the microprocessor that the TI-89, TI-92, and Voyage 200 graphing calculators use. Zilog makes the microprocessor for the TI-83 series of graphing calculators.

A

Ans

The last answer that was stored in the calculator. The calculator also keeps a history of the last few statements entered in on the home screen where general usage of the calculator occurs.

API

An Application Programming Interface is a set of methods or calls that the calculators provides to support requests made by programs.

App

A Flash application is an enhanced assembly program, with the primary differences being that it runs directly from the archive and its size is always in 16KB chunks (because of the calculator's internal memory design).

Arc

Archive is the permanent memory (also known as ROM) on the TI calculator. If your calculator crashes, all of your files in RAM will be lost, while everything in the archive will still be intact.

Arg

An argument is an expression that is supplied as input to a program, function, or command.

Asm

Assembly language is the other programming language available on the TI graphing calculators. It is much faster than TI-Basic, but it requires you to use a computer to compile it, which can be hazardous (namely, if you screw up in assembly, you can cause real damage to your calculator).

C

Cmd

A command is an instruction telling the calculator to do a particular task.

Cond

A condition is a statement or expression that evaluates to a true (1) or false (0) value.

D

Dec

A decimal is a number that has one or more digits after the period (i.e., 1.2345).

E

EOS

The Equation Operating System (EOS^TM) is the routine in the calculator that determines order of operations.

Equ

An equation is a mathematical expression involving variables and/or functions.

Err

An error is when an unexpected condition occurs, and the calculator displays a message to attempt to tell you what went wrong. Errors run the gamut from serious to stupid, meaning it might be time to buy a new calculator or you might have simply misused a command.

Expr

A combination of numbers, variables, and functions.

F

Frac

A fraction is the the result of division of two numbers (i.e., 5/7 or 1/3), including integers or even other fractions.

Func

A function is a command that returns a value of some kind (number, list, string, etc.).

FX

Special graphical or sound effects used in a game.

G

GUI

A graphical user interface is a type of user interface which allows people to interact with the calculator.

I

IDE

An integrated development environment is a software application that provides utilities for program development, usually including an editor and debugger.

Img

An image is a visual depiction of something.

Int

An integer is a whole number, either positive, negative, or zero.

I/O

Input is what you provide to the calculator when you press a key or select a menu, and output is how the calculator responds. The two are interdependent of each other.

L

Lib

A library is a program (usually made in assembly) that is designed to be an auxiliary utility for another program. Libraries many times provide functions that are not supported or not practical in TI-Basic (such as inverting the screen).

M

Matr

A matrix is a two-dimensional list (row by column) used for holding lots of information.

O

Op

An operator is a function that performs a set task.

OS

The operating system is the logic that controls the calculator.

P

Prgm

A program is simply the list of instructions that tells the calculator what to do to perform a task.

Pt

A point is a specific 1x1 space on the calculator's graph screen. You can use the Pt commands to manipulate a point. The primary difference between a pixel and a point is that a pixel is not affected by the graph screen settings, while a point is.

Pxl

A pixel is a specific 1x1 space on the calculator's graph screen. You can use the Pxl commands to manipulate a pixel.

R

Rand

A command used to generate a uniformly-distributed pseudo-random number between 0 and 1.

S

SE

Silver Edition is the more powerful version of the TI-83+ and TI-84+ calculators, with more memory and a faster processor.

Str

A string is a variable type that stores text as a series of symbols or tokens.

T

TI

Texas Instruments is the maker of the graphing calculators. In addition to calculators, they also make an assortment of other computer related products.

TI-83/84/+/SE

Shorthand way to refer to the five graphing calculators in the TI-83 series: TI-83, TI-83+, TI-83+SE, TI-84+, and TI-84+SE.

TIOS

The TI operating system is the built-in operating system that controls the calculator.

V

Var

A variable is a reference to the information that it holds. There are several different variables available in TI-Basic, including reals, lists, matrices, and strings.

Y

Y=

The built-in editor which is used to enter and edit the Y# functions.

Z

Z80

Zilog Z80 is the microprocessor that the TI-83 series of graphing calculators use. Motorola makes the microprocessor for the TI-89, TI-92, and Voyage 200 graphing calculators.
