If you ever wanted to tell what Operating System Mode you are using,
this /ditty/ will do the trick. It sets a global integer to a value
which represents the Mode being used. There is also a demo_prog at the
end of the unit.

var
OperatingMode : integer;
{ This integer holds a value of 0, 1, 2 or 3, which is an indicator
if the machine is in:
Dos Mode (0),
Windows Standard Mode (1),
Windows Enhanced Mode (2),
DESQview mode (3); }
