Planning your menus

Several considerations are important when planning a menu. Details are presented throughout this topic, but some general rules include the following:

• You must include an EXIT or LOGOUT command in the menu to be able to leave the menu. For security reasons, the <Esc> key does not work.

• The maximum number of windows per menu is 11 (1 main window and 10 subwindows).

• The maximum number of menus you can define in a single file is 255.

• The maximum ``MENU'' name length (title bar) is 40 characters.

• The maximum number of ``ITEM'' lines per window is 12.

• The maximum width of each window ``ITEM'' is 40 characters.

• The maximum text file width is 78 characters.

• The main menu must be at the beginning of the .SRC file.

• Submenus defined in the same file are called with the SHOW command by menu number.

• Menus in separate files are called as submenus, by menu name, with the LOAD command.

• If a command wraps to another line, you should type a plus sign (+) at the end of the line and continue the command on the next line.

• Menu colors are determined by the settings in the COLORPAL utility. See ``COLORPAL''.
