title => 'Default' );

ABSTRACT
UI::Dialog::Backend::ASCII is the UI::Dialog backend for the native Perl mode of basic text. The widgets are very much "rigid" in that the width and height arguments are completely ignored.DESCRIPTION
This backend is intended as a last resort mechanism in that no other dialog variant has been found and so this, the most absolute of bargain basement dialog variant interfaces, is used instead.EXPORT
- None
