<XA>,<YA>

The coordinates are counted from the lower left and beginning with 0.

If < _ L B A D or U precedes the value for <Align> of the X coordinates, the left  side of the object to be placed (an overlay picture, a filled rectangle, etc.) is placed at the specified position.   In front of a Y coordinate means that this value determines the base point of the rectangle or picture.   If * M or K precedes the coordinates the middle of the object is placed at these coordinates.   Correspondingly, the characters > ^ R J T and F refer to the right or top edges of the rectangle or picture. Without any value input, there are basic defaults which are dependent on the command at hand.   Therefore, an [O:] command places an overlay picture without an <X> horizontal value in the middle of the picture. And without a <Y>, at the top of the existing base picture.   A pantograph placed with the [E:] command is, however, positioned at the top of the picture automatically, as it should rest at the top in order to depict contact to an overhead wire.
