CIRCLEName:
Coordinates for the circle can be specified in the following ways:
where <x1> is a number or parameter in the decimal range 0 to 100 that specifies the x coordinate for one end of the diameter of the circle; <y1> is a number or parameter in the decimal range 0 to 100 that specifies the y coordinate for one end of the diameter of the circle; <x2> is a number or parameter in the decimal range 0 to 100 that specifies the x coordinate for the other end of the diameter of the circle; This syntax is used for absolute screen units.
where <x1> is a number or parameter that specifies the x coordinate for one end of the diameter of the circle; <y1> is a number or parameter that specifies the y coordinate for one end of the diameter of the circle; <x2> is a number or parameter that specifies the x coordinate for the other end of the diameter of the circle; and <y2> is a number or parameter that specifies the y coordinate for the other end of the diameter of the circle. This syntax is used for absolute data units.

This syntax is used for relative screen units.
