EQW version 1.18

Author: E.W.

EQW is a graphical equation editor created by E.W. for the Texas Instruments TI-89 and TI-92+ calculators. With EQW, you create and edit equations and expressions in a graphical format, instead of the usual command-line format. With EQW, it is easier to create and edit expressions without typographical errors. The expression is displayed in 'pretty-print' format, as you enter it. Since EQW can evaluate expressions and subexpressions, you can also use EQW as a calculation environment. This feature is further enhanced in that EQW supports the STO operator, the 'with' operator |, and most built-in functions and commands. You can also call EQW from TI-Basic programs.
