Implementing Menus You can use TACL to define menus. A menu displays a screen and allows users to
press function keys to access information and utilities.
Use the text variable in Figure 2-14, menu, to generate a menu. The user can press
function keys to start applications and utilities. Note that the menu text could be
displayed by individual #OUTPUT calls within the #LOOP function; setting
displayvar to the display text avoids multiple #OUTPUT calls. To run this code,
load the file that contains the code and type menu.
