Video display modes is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
The task is to demonstrate how to switch video display modes within the language. A brief description of the supported video modes would be useful.
Locomotive Basic
The Amstrad CPC464 supports three video modes:
- Mode 0 - Graphics: 160x200 Text: 20x25 Colours: 16
- Mode 1 - Graphics: 320x200 Text: 40x25 Colours: 4
- Mode 2 - Graphics: 640x200 Text: 80x25 Colours: 2
Note that text can be displayed using conventional means in all display modes.
