Int 62 Fn 0046  u - Fgdriver V3.03 - "fg_getyjoy" - Get Vertical Position  [V]

   AX = 0046h
   BX = joystick number (0001h or 0002h)

Return: AX = vertical position of joystick
       FFFFh if joystick uninitialized or not present

Notes: For FGDRIVER v1.10, this function was "FG_GETMAP" (see AX=003Ch);
     "FG_GETYJOY" was AX=0077h
   The actual coordinates are processor- and joystick-dependent
   You must call "FG_INITJOY" (AX=004Dh) before using this function
