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. -- Regards Ray
