Chapter 20 Customizing menus and keyboard Through the use of the many calculator menus you have become familiar with the operation of menus for a variety of applications. Also, you are familiar with the many functions available by using the keys in the keyboard, whether through their main function, or by combining them with the left-shift („), right-shift (,) or ALPHA (~) keys. In this Chapter we provide examples of customized menus and keyboard keys that you may find useful in your own applications. Customizing menus A custom menu is a menu created by the user. The specifications for the menu are stored into the reserved variables CST. Thus, to create a menu you must put together this variable with the features that you want to display in your menu and the actions required by the soft menu keys. To show examples of customizing menus we need to set system flag 117 to SOFT menu. Make sure you do this before continuing (See Chapter 2 for instructions on setting system flags). The PRG/MODES/MENU menu Commands useful in customizing menus are provided by the MENU menu, accessible through the PRG menu („°). Setting system flag 117 to SOFT menu, the sequence „°L @)MODES @)MENU produces the following MENU soft menu: The functions available are: MENU: Activates a menu given its number CST: Reference to the CST variable, e.g., ,@@CST@@ shows CST contents. TMENU: Use instead of MENU to create a temporary menu without overwriting the contents of CST RCLMENU: Returns menu number of current menu Page 20-1
