How can start to do the program in ti-89 im study civil engineer, and a have programs in fortran


You can find the program editing menu under "Apps". Choose "New..." After you enter the name of your program, you will be able to edit it. To run it, go to the home screen (the screen where you enter mathematical equations), hit 'catalog', then 'f4', and choose the program from the list.

As for the coding itself, this site has a solid reference of many concepts and commands that are involved when programming for the TI-89: http://tibasicdev.wikidot.com/68k:home The best way to learn, however, is to play around and figure things out yourself. Programming for the TI-89 is much more powerful than it is for the previous TI calculators. Best of luck!

kinda. The TI-85 programs differently, lacks a table feature, is not upgradable, has redefinable keys, has a larger screen, is smaller, energy efficient, TI-86 semi-compatible, and is older.
The TI-84+ has archive memory, flash-upgradable, FSTN (clearer) screen, 16*8 screen, USB On-The-Go compliant, almost a centimeter longer, assembly language support, and a tad bit faster.

Free TI-85: $0
TI-84 plus: $119.99
TI-84+SE: $129-139
