How to control form position and size (1 Viewer)

How do you keep forms from anchoring to the upper right and being really big. I used the code below, but is there more code that would prevent this?:

Normally forms anchor at the upper left. In Windows coordinates, <0,0> is the left-most, upper-most available coordinate on the screen. Window growth is thus down and to the right. What you are using is the way most people do this unless they maximize the screen instead.
