If I recall correctly then every program starting with a char equal to
or greater than 'A' (?)will be listed. The only thing with chars
greater than 'theta' (?) is that they are not selectable in the PRGM
menu. If and only if your program menu is longer than 7 items, then
those programs won't be displayed. In all other menus these programs
are visible, so you can delete them for instance.
