Appendix B. TI-BASIC command reference
TI-BASIC comprises many commands for interacting with users, creating graphics, manipulating program flows, and working with math concepts. Throughout the first 11 chapters, many commands are discussed; this appendix presents all of these commands, plus extras, as an easy-to-use tabular reference. Each section references the chapters where the concepts in that section are first introduced, so that you can look back for more detail.
This appendix is organized to mirror the progression of the chapters. Input and output are first introduced, followed by the control-flow commands. The third section focuses on the many TI-BASIC commands to manipulate graphics and functions on the graphscreen. Math and data manipulation commands are presented fourth, and the appendix concludes with the hybrid BASIC commands.
Each command is presented with a short description and a sample usage scenario. For some commands, the arguments are shown separately where I feel additional clarity is necessary. Unless otherwise specified, arguments shown in square brackets ([ and ]) are optional and may be omitted. To prevent confusion, optimizations such as omitting closing quotes and parentheses are not performed in the Usage column. Many commands can be found in their own menus. Most can be found in the Catalog, [2nd][0]. Variables such as strings and pictures are in the [VARS] menu.
