I am trying to use AmigaDOS I/O (as described in the Appendix, "Console
Input and Output on the Amiga" of the AmigaDOS manual) to mouse select
button presses and the pointer position at button press.

Writing the SRE, Set Raw Events, Amiga specific CSI sequence for request
2, RAW mouse input, and 4, Pointer position, looks like it should do it.

I do get back the mouse button down and up response sequences, but the
<x>,<y> values are almost always "0;0;". Clicking and moving as fast as
possible will sometimes result in a small positive or negative <x> or <y>
value, as if it were relative to the position 0.1 sec before.

Is there something more I need to do to get the <x>,<y> positions to
be the window position of the pointer, or is this part of the
implementation that did not make it off the paper?

Thanks for any help.
