Syntax	drawoval (x, y, xRadius, yRadius, Color : int)
Description	The drawoval procedure is used to draw an oval whose center is at (x, y). The horizontal and vertical distances from the center to the oval are given by xRadius and yRadius.
Example	This program draws a large oval that just touches each edge of the screen using color number 1. The maxx and maxy functions are used to determine the maximum x and y values on the screen. The center of the oval is at (midx, midy), which is the middle of the screen. setscreen ("graphics") const midx := maxx div 2 const midy := maxy div 2 drawoval (midx, midy, midx, midy, 1)
Execute
Details	Ideally, a circle is drawn when xRadius = yRadius. In fact, the aspect ratio (the ratio of height to width of pixels displayed on the screen) of the IBM PC compatibles is not 1.0, so this does not draw a true circle. In CGA graphics mode this ratio is 5 to 4. The meaning of the Color number depends on the current palette. See the palette statement. The screen should be in a "graphics" mode. See the setscreen procedure for details. If the screen is not in a "graphics" mode, it will automatically be set to "graphics" mode.
