TMENU
Type: Command
Description: Temporary Menu Command: Displays a built-in menu, library menu, or user-defined menu.
TMENU works just like MENU, except for user-defined menus (specified by a list or by the

like a custom menu, but are not stored in reserved variable CST. Thus, a menu defined and
displayed by TMENU cannot be redisplayed by evaluating CST.
See Appendix H for a list of the calculator’s built-in menus and the corresponding menu
numbers (x
