初学,碰到个问题不知是什么回事?

Intel汇编语言程序设计(第四版)的一个例了AddSub2.asm
代码如下:

TITLE Add and Subtract, Version 2 (AddSub2.asm)

; This program adds and subtracts 32-bit integers
; and stores the sum in a variable.
; Last update: 2/1/02

INCLUDE Irvine32.inc

.data
val1 dword 10000h
val2 dword 40000h
val3 dword 20000h
finalVal dword ?

.code
main PROC

mov eax,val1 ; start with 10000h
add eax,val2 ; add 40000h
sub eax,val3 ; subtract 20000h
mov finalVal,eax ; store the result (30000h)
call DumpRegs ; display the registers

exit
main ENDP
END main

当编译时出如下提示:

There were 2 errors detected
这两个错误是什么意义?

没有找到ExitProcess,DumpRegs函数吧！

Irvine32.inc呢？

Irvine32.inc 也拷贝到了同一个目录下了的呀。
