User manual TEXAS INSTRUMENTS CBL 2

[. . . ] In addition, for the TI-83 Plus we have provided versions of these programs in the form of an application. You can download applications to the calculator using TI-GRAPH LINK or the Flash Installer provided by TI. (The Flash Installer currently is not available for the Macintosh, so Macintosh users will need to install the standalone programs using TI-GRAPH LINK. ) When you load an application into the calculator, it is put in the Flash ROM, so it does not take up space in RAM. To use an application, press 9 and select the application name from the APPLICATIONS menu. How to Install the Application Using the Flash Installer The Flash Installer is currently available only for the Microsoft® Windows® platforms (Windows® 3. 1, Windows® 95, and Windows NT®). [. . . ] 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. 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. 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. If you select the GOTO option, the calculator will show which line caused the error. ERR:DUPLICATE NAME Before the CBL application runs a selected program, it first checks to see whether a program with that name already exists in the calculator. If a program with the same name already exists and is archived, the application will display an error message and exit. The application cannot create another program with the same name in RAM as one in the archive. You must either delete the existing archived program, rename it, or unarchive it into RAM to be used in place of the built-in application version. If a program with the same name already exists and is protected, the application will display an error message and exit. The application will not replace a protected program with its own version. [. . . ] 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. [. . . ]
