<U>y</U> = <B>POINT</B>({<U>x</U>,<U>y</U> | <U>n</U>})
|

Returns the attribute of a specified screen coordinate or coordinate
|
||
|
|
information about the current screen location.

|
<U>x</U>,<U>y</U> Screen coordinates. POINT(<U>x</U>,<U>y</U>) returns the attribute of
|
||
|
|
the screen location specified by the two arguments. The
|
||
|
|
screen coordinates must be given in absolute form (STEP is
|
||
|
|
not allowed). If either coordinate is out of range, POINT
|
||
|
|
returns -1.
|
||
|
|
|
||
|
|
<U>n</U> Must be 0, 1, 2, or 3. POINT(<U>n</U>) returns the following
|
||
|
|
information about the current screen location:
|
||
|
|
|
||
|
|
If <U>n</U> = 0 the current physical x coordinate.
|
||
|
|
If <U>n</U> = 1 the current physical y coordinate.
|
||
|
|
If <U>n</U> = 2 the current world x coordinate, if WINDOW is
|
||
|
|
active; otherwise, the current physical x coordinate.
|
||
|
|
If <U>n</U> = 3 the current world y coordinate, if WINDOW is
|
||
|
|
active; otherwise, the current physical y coordinate.
