同样的程序在Multisim和Keil C编译不一样

[南气子水]

ORG 0000H
AJMP MAIN
ORG 000BH
AJMP INT0_SUB
ORG 0030H
MAIN: MOV SP,#70H
MOV TMOD,#00H
MOV IE,#82H
SETB P1.0
MOV TH0,#63H
MOV TL0,#18H
SETB TR0
LOOP: AJMP LOOP

DJNZ R2,YAS1
MOV R2,#0C8H
CPL P1.0
YAS1: MOV TH0,#63H
MOV TL0,#18H

RETI
END

在Keil C里的信息：

"shanruo_2" - 0 Error(s), 3 Warning(s).

Multisim中的编译信息：

“没有头文件，鬼才知道SP、TMOD、IE都是什么符号……”
是的，MultiSim就是这么想的。

Ejack79 说话很风趣啊
头文件是哪个呢？

刚刚查到 貌似是 htc.h
因为 multisim 用的 Hi-tech的 单片机

鄙视 某些同学 为啥不贴出来呢
唉！
