Referencing text within menu items and sub-menu item titles
Variables enable you to write menu item descriptions and sub-menu item titles so
that they refer to a specific variable and value. This function enables you to
customize menu item descriptions and sub-menu item titles that are displayed
during the installation process.
For example, if you were to expand the previous example, you could construct the
language list menu item “Language Menu” so that it would display the correct
operating system during the installation process, no matter what operating system
menu item was selected.

item descriptions are displayed during the installation process, do the following:

maps is displayed.

example above, you would select the Language Menu menu item.
