DH and DL are the two components of DX.  8086 registers are
two bytes - just like the Reg.DX integer is two bytes.  But
these are occasionally accessed by each byte - half a
register.  In QuickBASIC, this is accomplished with:

     Month% = Reg.DX \ 256    ' Note the Backslash (integer division)
     Day%   = Reg.DX MOD 256  ' Mod gives the remainder - the lower byte
                              ' of DX.  The integer division gives the
                              ' higher byte.

 JB> DayofWeek% = reg.al  'values?

Thus, this would be:
     DayofWeek% = Reg.AX MOD 256
