{
  _asm {
	mov dl, k
	mov cl, 16
	sub cl, dl
	mov eax, [wordval]
	shr eax, cl
           }
}

WORD WORD_hi_lo(BYTE byte_high,BYTE byte_low)
{
	_asm {
		mov ah,byte_high
			mov al,byte_low
	}
}

SWORD get_svalue(BYTE k)
{
	_asm {
		xor ecx, ecx
			mov cl,k
			mov eax,[wordval]
			shl eax,cl
			shr eax, 16
			dec cl
			bt eax,ecx
			jc end_macro
signed_value:inc cl
			 mov ebx,[start_neg_pow2]
			 add ax,word ptr [ebx+ecx*2]
end_macro:
}
