in openGL how can I make the left of the screen = 0 and the right to = 10 or somthing, and the top = 0 and the bottom = -10. because i dont like working with numbers only ranging from -1.0 to 1.0. i read here that the coordinate system could be whatever you wanted it to be but so far i have not found a command that changes it.

For 2d use gluOrtho2d(...);
With 3d you will just have to adjust.

Adjust by using glTranslatef, to the whole screen.
