Hi David - glad you liked the article! I agree, TheDraw was a great DOS program for drawing ASCII art. As you mentioned, you can output the file to see it in full color. Use TYPE on FreeDOS, or 'cat' on Linux. You'll need to load an ANSI driver on FreeDOS, like the open source NANSI.SYS driver. Linux terminals are modified color ANSI terminals, so should display ANSI escapes by default.

Another way to write this program for DOS is to copy the array directly to video memory. But I thought showing it "character by character" using _setbkcolor and _settextcolor would help others to make their own programs with color text. :-)
