what strings or formats are send by mouse clicks

[Timo Krijnen]

I am extending a program that allows the user of our ABC system (a
programming language embedded in an editor that "understands" the
language) to redefine her key bindings easily.

One of the editor operations is the [mouse] operation: after a mouse
click it should change the "focus" (the standing out part of the
program text that other operations, like [delete] work on) to the
position where the mouse points at.

I implemented a scheme, that understands mouse clicks sending
parameterized strings a la termcap(5), where the row and column must
have the %d, %2, %3, %+x or %-x formats, possibly combined with %i and %r.
(E.g. our VT100 emulation under Xterm sends "\033[M %r%+!%+!" when the
left button is pressed).

Does anyone know whether there are machines/terminals that send the
position of a mouse click in some other way?

Are there machines/terminals where you must sense the terminal or
screen AFTER a mouse click to get the position returned? (E.g. like
the good old HP 2640b terminal, where the arrow keys work locally at
the terminal only, and you must sense the terminal for the correct
cursor position).

Does anybody know what the various mice for MS-DOS machines send?
