: did you actually read what it says on that page:

: "Once Ansi.sys has been loaded, it's various functions can be accessed at 
: any time by sending one or more "Escape Sequences" to the screen. An Escape 
: Sequence comprises three parts: "

I sure did.  I guess I just didn't understand it completely.

: and it is right there toward the top of the page. note the key phrase "Once 
: Ansi.sys has been loaded".

I wasn't sure what "ANSI.SYS" was, but I remembered having seen it on older
(pre-Win3.1, even) PCs during boot-up, so I shook my head to
try to clear the confusion, assumed that DOS was somehow using ANSI.SYS
already.

: so, decide if you want to use ansi.sys. if you do, then load it.
: otherwise, look at the documentation for conio functions.

huh.  I guess my question is more basic, then.  Rather than ask anyone to 
debug my program, I just want to know how to clear the screen from inside 
a C program.
