This is really a DOS specific question but I have directed followups
to comp.programming because I want to discuss your general strategy.

Don't do this.  If you must change the meaning of a mouse button use
another button to do this.  Your method requires your users to have
their hands on two different devices in order to do input.  In fact
why not just make use of the different buttons on the mouse?  You could
for example increment by 1 on the left, 5 on the right and 3 on the
middle.  If your user has a two button mouse it still works but with
less intermediate control.
