Overview of the 'Low Level' Mouse routines:

     The Expand libaray comprises a set of functions that make controlling
     the Mouse in text mode possible. The Functions found in this part of
     the documentation are all 'Low Level' Mouse functions, meaning that they
     perform some simple task directly on the Mouse Driver (MOUSE.COM
     generally). The routines in the next section ('High Level' Mouse
     functions) all use the primary functions of this part to interface with
     the Mouse.

     Programming the Mouse is quite special and can be confusing some times,
     Read the documentation to be well informed, and for some tips.

     Note that the functions here have no direct effect on the Video, except
     for the Mouse Cursor itself.
