Texas Instruments TI-92+, Tip List

ASM limit
This is an artificial limit to the size of compiled programs that can be run on the TI-89 / TI-92 Plus. TI
enforces this limit to prevent software piracy (theft) of a few large, for-pay applications. The ASM limit
unfortunately also severely limits the program functionality that can be implemented by independent
developers. The ASM limit was originally 8K bytes, but was later increased to 24K bytes.
assembler, assembly See asm.
Auto, Exact, Approx modes
The modes in which the TI-89 / TI-92 Plus can be set, to evaluate expressions. In Exact mode, all
calculations are performed with exact values for constants. In Approx mode, all calculations are
performed with floating-point approximations of numeric constants. In Auto mode, the calculator
attempts to use the 'best' mode (either Exact or Approx) to evaluate the expression. If an expression
includes constants with decimal points, Approx mode will be used. The mode is set in the Mode
screen, which is displayed when the [MODE] key is pressed.
Automatic Power Down™. See APD.
Auto-paste
A calculator home screen feature. Use [UP] and [DOWN] to highlight an entry or answer in the home
screen, then press [ENTER] to paste the expression to the current cursor position in the entry line.
auto-repeat
The cursor movement feature by which the cursor will automatically move if the cursor keys are
pressed and not released.
auto-simplify
The process by which the calculator automatically simplifies symbolic expressions. Expressions are
simplified to put them into a standard form. Auto-simplification may sometimes be desired, but often it
makes some algebraic operations difficult or impossible. Auto-simplification cannot be disabled on the
TI-89 / TI-92 Plus.
backup, back-up
A complete copy of the memory of the calculator that is stored on a PC. May also refer to the act of
creating a backup. GraphLink software is used to create a backup. Restoring a backup means to copy
the backup from the PC to the calculator.
backup battery
The lithium coin cell in the TI-89 and TI-92 Plus which maintains RAM contents if the main batteries
discharge or are replaced.
base code
An alternative TI term for AMS; see AMS.
benchmark
A program or test case with the sole purpose of evaluating some aspect of the performance of the
calculator or computer. Accuracy, correctness, speed or code size may be tested.
binary
Refers to numbers expressed in the base-2 number system. The TI-89 / TI-92 Plus can represent
integers in base-10 (decimal), binary and hexadecimal (base-16).
black-bar See crash.
