Procedure Bitwise(a, b)
Debug a & b ; And
Debug a | b ;Or
Debug a ! b ; XOr
Debug ~a ;Not
Debug a << b ; shift left
Debug a >> b ; arithmetic shift right
; Logical shift right and rotates are not available
; You can of use inline ASM to achieve this:
Define Temp
; logical shift right
!mov edx, dword [p.v_a]
!mov ecx, dword [p.v_b]
!shr edx, cl
!mov dword [p.v_Temp], edx
Debug Temp
; rotate left
!mov edx, dword [p.v_a]
!mov ecx, dword [p.v_b]
!rol edx, cl
!mov dword [p.v_Temp], edx
Debug Temp
; rotate right
!mov edx, dword [p.v_a]
!mov ecx, dword [p.v_b]
!ror edx, cl
!mov dword [p.v_Temp], edx
Debug Temp
