  • Third-Party Editors: Tools like TI-BASIC Developer or SourceCoder 3 (online) allow you to write TI-BASIC code in a user-friendly environment and export tokenized programs for transfer.
  • Program Structure: Each program begins with the keyword PROGRAM: followed by the program name. Commands and statements follow in sequence.

Example of simple TI-BASIC program to calculate the factorial of a number:

PROGRAM:FACT
:Input "N?", N
:1→F
:For(I,1,N)
:F*I→F
:End
:Disp "FACTORIAL=", F

To transfer this program from a third-party editor or after conversion, save it as a .8xp file and use TI Connect™ CE to send it to your calculator.
