HIGH             Return high-order                                   Operator

  HIGH expression                       ; Ideal or MASM mode

    Returns the high 8 bits of expression.


  addrtype HIGH expression              ; Ideal mode

    Converts expression to the specified address subtype (type override).
    addrtype must be smaller in size than the type of the expression; the
    resulting address is adjusted to point to the high part of the object
    described by the address expression.

    Examples:   Ideal
                big     dd      12345678h
                mov     ax,[WORD big]                   ;ax = 5678h
                mov     al,[BYTE PTR big]               ;al = 78h
                mov     ax,[WORD HIGH big]              ;ax = 1234h
                mov     ax,[WORD LOW big]               ;ax = 5678h
                mov     al,[BYTE LOW WORD HIGH big]     ;al = 3rd byte = 34h
