介绍用Java解析网络数据的三种特殊方法

#make_BIN#

; This sample shows how
; CMP instruction sets the
; flags. 

; Usually CMP instruction
; is followed by any relative
; jump instruction such as:
; JE, JA, JL, JAE...

; NOP instruction does
; nothing (no operation).

; It is recommended to open:
; "Lexical Flag Analyzer"
; and "Flags"
; from emulator's "View"
; menu before running
; this code.

; (Signed/Unsigned)
; 4 is Equal to 4
MOV AH, 4
MOV AL, 4
CMP AH, AL
NOP

; (Signed/Unsigned)
; 4 is Above and
; Greater then 3
MOV AH, 4
MOV AL, 3
CMP AH, AL
NOP

; -5 = 251 = 0FBh

; (Signed)
; 1 is Greater then -5
MOV AH, 1
MOV AL, -5
CMP AH, AL
NOP

; (Unsigned)
; 1 is Below 251
MOV AH, 1
MOV AL, 251
CMP AH, AL
NOP

; (Signed)
; -3 is Less then -2
MOV AH, -3
MOV AL, -2
CMP AH, AL
NOP

; (Signed)
; -2 is Greater then -3
MOV AH, -2
MOV AL, -3
CMP AH, AL
NOP

; (Unsigned)
; 255 is Above 1
MOV AH, 255
MOV AL, 1
CMP AH, AL
NOP
