Use left or right mouse button to draw (just for fun) in DOS.

funwithmouse is a dos app where you can use left or right mouse button to
draw, just for fun. The point is to demonstrate the use of mouse in DOS using
mouse interrupt 33h from assembly language. The assembly language function can
itself be called by compiling the assembly language program as a binary file and
using CALL ABSOLUTE in QuickBASIC, or by compiling the program as a library
that can converted to a Quick library (QLB) and declaring the subroutines and
functions.
