User manual TEXAS INSTRUMENTS CBL 2

[. . . ] The functions that the programs perform are essentially unchanged from the TI-83, but cosmetic changes have been made where necessary. In addition, for the TI-83 Plus we have provided versions of these programs in the form of an application. Application files have . app file extensions on the PC. You can download applications to the calculator using TI-GRAPH LINK or the Flash Installer provided by TI. [. . . ] To run the program: · Press the number in front of the program name -- or -- · Use to highlight the program name and press Í. To move around the main menu: · Use } and to move one line at a time. · -- or -- } or to move one screen at a time. You can quit the application from the main menu by pressing y K or by selecting the QUIT option listed on the menu. Once you select a program from the menu, that program begins running. The programs run nearly identically to the way they did on the TI-83. When you quit a program by selecting a QUIT option or the program ends normally on its own, you return to the application main menu, where you may select a new program to run or exit the application. (To exit, press ` or 2 K. ) © 1999 Texas Instruments Incorporated 2 Error Messages ERR:BREAK If you press É while a program is running, you will see a screen with the message ERR:BREAK. This means that you have not only quit the program currently executing, but also exited the entire application and returned to the Home screen. ERR: MEMORY The calculator can store up to ten "pages" of applications. These pages can be divided among different applications. Data in the calculator Archive reduces the number of pages available to applications. In order to run a selected program, the application must load the program into RAM, so there must be enough free RAM available. If there is not enough RAM to run the selected program, the application will exit and you will see a screen with the message ERR: MEMORY. You should make more RAM available by deleting or archiving items currently in RAM, and then run the application again. If the application exits normally, or because of a break or out-of-memory error, it automatically removes the TI Basic programs that it loaded into RAM. Other errors Other types of errors may occur while you are running a program. If any other type of error occurs, the application will exit and you will see a screen beginning with ERR:, followed by the type of error. Such an error often indicates that the activity was not performed in the proper sequence as described by the activity, or that data collected from the CBL was in error. When such an error occurs, the TI Basic program(s) that the application loaded into RAM are not removed automatically. Since they remain in RAM, the error screen provides a GOTO option. If you select the GOTO option, the calculator will show which line caused the error. This may help in diagnosing the problem. [. . . ] In the application, when the graph is drawn you are automatically put into Trace mode. After tracing, you should press the Í key to continue running the program. This change was necessary so that you would not have to repeatedly re-start the application. Some of the descriptions in the activity book are written assuming the behavior is that of the stand-alone program. [. . . ]
