Menu numbers (RCLMENU and MENU functions)
Each pre-defined menu has a number attached to it. For example, suppose that
you activate the MTH menu („´). Then, using the function catalog
(‚N) find function RCLMENU and activate it. In ALG mode simple press
` after RCLMENU() shows up in the screen. The result is the number 3.01.
Thus, you can activate the MTH menu by using MENU(3.01), in ALG, or
3.01 MENU, in RPN.
Most menus can be activated without knowing their numbers by using the
keyboard. There are, however, some menus not accessible through the
keyboard. For example, the soft menu STATS is only accessible by using
function MENU. Its number is 96.01. Use MENU(96.01) in ALG mode, or
96.01 MENU in RPN mode to obtain the STAT soft menu.
Custom menus (MENU and TMENU functions)
Suppose that you need to activate four functions for a particular application.
Say, that you need to be able to quickly access the functions EXP, LN, GAMMA
and ! (~‚2) and you want to place them in a soft menu that you will
keep active for a while. You could do this by creating a temporary menu with
function TMENU, or a more permanent menu with function MENU. The main
difference is that function MENU creates variable CST, while TMENU does not.
With variable CST created permanently in your sub-directory you can always
reactivate the menu using the specifications in CST by pressing „£. With
TMENU the menu specifications are lost after you replace the temporary menu
with another one.
For example, in RPN mode, a menu is created by using:
{EXP LN GAMMA !} ` TMENU `
or
{EXP LN GAMMA !} ` MENU `
to produce the following menu:
Note: The number 96.01 in this example means the first (01) sub-menu of
menu 96.
