I have been trying to work this out for a while, DBPro comes with a clear screen command cls which clears the entire screen, but is it possible to only clear part of the screen so something like cls top of cleared screen, left of cleared screen, bottom of cleared screen, right of cleared screen.

I probably havent explained this very well so feel free to ask if you don't get what im asking about.

Thanks anyone who knows anything about this.

p.s. my program allows you to draw on the screen and is only in 2D - if that helps in any way.

well you could always do this: instead of CLS, do CLS and then render just what you need ... I'm not sure but I don't think DBPro has a built-in method for what u need

Could you help me treat my injured Dino-Fly ?

Well, if you need certain parts of the screen to not leave trails over them and things like that then you could just use the BOX command over the area you want to clear. I might not have understood completely, so sorry if this doesn't help.

The BOX command is the way you do it:


If you don't provide the colour parameters, then it will use the current ink colour. The colours can all be different to give various effects too.
