* COLOR uses the OS/2 ANSI driver to set screen foreground and
* background colors in protected mode. Syntax is:
*
* COLOR fb
*
* where f = foreground color (X,x,B,b,G,g,C,c,R,r,M,m,Y,y,W,w), and
* b = background color (x,b,g,c,r,m,y,w)
*
* Compile and link with: cl -Lp -G2 color.c

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
