BYTE 0dh,0ah

BYTE "1. x AND y"     ,0dh,0ah

BYTE "2. x OR y"      ,0dh,0ah

BYTE "3. NOT x"       ,0dh,0ah

BYTE "4. x XOR y"     ,0dh,0ah

BYTE "5. Exit program",0

msgAND      BYTE "Boolean AND",0

msgOR       BYTE "Boolean OR",0

msgNOT      BYTE "Boolean NOT",0

msgXOR      BYTE "Boolean XOR",0

msgOperand1 BYTE "Input the first 32-bit hexadecimal operand: ",0

msgOperand2 BYTE "Input the second 32-bit hexadecimal operand: ",0

msgResult   BYTE "The 32-bit hexadecimal result is:            ",0

caseTable   BYTE '1'     # lookup value

DWORD _AND_op        # address of the procedure

EntrySize = ($ - caseTable )

   BYTE '2'

   DWORD _OR_op

   BYTE '3'

   DWORD _NOT_op

   BYTE '4'

   DWORD _XOR_op

   BYTE '5'

   DWORD _ExitProgram

NumberOfEntries=($ - caseTable)/EntrySize

.code

   cmp al, '5' # is selection valid (1-5)?

   ja L1   # if above 5, go back

   cmp al, '1'

   call Crlf

   call **BLANK**

   jc quit # if CF = 1 exit

   call Crlf

   jmp Menu    # display menu again
