On the NG I posted this program to show how easy it is to draw the French Flag on the Oric, with BASIC...
1 TEXT:PAPER0:INK2:HIRES
2 CURSET 6,0,3:FILL 200,1,20
3 CURSET 84,0,3:FILL 200,1,23
4 CURSET 162,0,3:FILL 200,1,17
Which gives us...

Obviously, it would look a whole lot better if the background were in black!
(Was unsure which forum to post this in, so just picked one. Also wanted to test the Img function - which seems to work just great.)
