I'm new to QBASIC and we are starting to use it in my computer class. In fact we are using it to make graphics, and I am trying to create a Scooby Doo face; but I don't know where to start. Can anyone help me?

well, first you gotta set the screen mode: this can be done with screen (http://qbasicnews.com/qboho/qckscreen.shtml) once you're in, you can use a host of graphical commands to draw things on to the screen.
por ejemple: http://qbasicnews.com/qboho/qckline.shtml http://qbasicnews.com/qboho/qckcircle.shtml http://qbasicnews.com/qboho/qckpset.shtml http://qbasicnews.com/qboho/qckpaint.shtml http://qbasicnews.com/qboho/qckpalette.shtml another example: screen 7 ' 320x200x16c line (0, 0)-(319, 199), 4 this draws a line from coordinate (0, 0) to (319, 199). you get the picture

A *lot* of newer graphics chips do *not* support the old EGA low-res modes. SCREEN 7 (mode Dh) is one of them. I have a couple 'newer' cards which do not support them. You may find that the ones at your school do not either. SCREEN 13 (mode 13h) is a better choice, it is still supported by all cards and allows for 256 colours instead of 16.

TIP:
1. Get a scooby Doo image over the net 2. Save as 235 BMP in 320*200 3. Load with CosmoX,DQB or any lib you like.. :*)

Quote:Depending on the teacher, that will either get full marks or zero.yeah, but come on, seriously, drawing a scoobey doo face in qbasic could be hard for a beginning programmer (I consider myself and advanced-beginner and I don't think that I could draw a scoobey doo face) -Nova

One night I had a dream where I was breaking balls. The next morning, BALLSBREAKER was born. Quote: Excellent. Now you can have things without paying for them. BALLSBREAKER 2 ~-_-Status Report-_-~ Engine: 94% Graphics: 95% Sound: 100% A Severe Error has crippled BB2 for the time being... I have to figure it out, but until then you won't see much of it  .-----------------------------

I guess the teacher expects them to find a scooby doo picture and break it up into its sub-parts of circles, ovals, and lines on graph paper. Then write or type down the coordinates and add in LINE / CIRCLE / PAINT / DRAW to it.
