Rainbow 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.
- Task
- Print out the word 'RAINBOW' to the screen with every character being a different color of the rainbow.

The Raspberry Pi versions of the language require a graphic mode for colored text (unlike the MS-DOS versions), but they compensate by supporting this unusual string indexing (which only works with the interpreted MS-DOS version).
char I;
[SetVid($13); \set 320x200x8 VGA graphics
for I:= 0 to 6 do
[Attrib(32+I+I); \set color attribute
ChOut(6, I("RAINBOW "));
];
]
