	The problem of the ST is his graphic-mode where also all text
will be put out. To get a charackter from the screen, you first have
to calculate the Postion in the graphic-screen, then compare the
current 8 * 16 (or 8 * 8) field with the current systemfont. You see,
it is a lot of work, so the (nearly) only possible language is assembler.

	As I know, gemdos doesn't support such a function, but perhaps
later it will do it :-).
