我只是跟随教师的视频，无法摆脱错误。 我希望我是个白痴，错过了什么。请帮忙。谢谢！ 我的代码如下所示：
; Title: Poject 00
; Name: Flamo
; Course/Project ID: CS271
; Description: It will ask for name/age input
.386
.model flat,stdcall
.stack 4096
ExitProcess proto,dwExitCode:dword
DOG_FACTOR = 7
.data ; declare variables here
userName BYTE 33 DUP(0) ; string to be entered by user
userAge DWORD ? ; integer to be entered by user
intro_1 BYTE "Hi, my name is Flamo, and I am here to tell you your age in dog years", 0
prompt_1 BYTE "What is your name? ", 0
intro_2 BYTE "Nice to meet you " , 0
prompt_2 BYTE "How old are you? ", 0
dogAge DWORD ?
results_1 BYTE "WOW THAT's ", 0
results_2 BYTE " IN DOG YEARS!!!!!!!" , 0
goodbye BYTE "BYE BYE! " , 0
.code
main proc ; write your code here
; Introduce programmer
mov edx, OFFSET intro_1
call WriteString
call CrLf
; get user name
; get user age
; calculate dog years
; output results
; say goodbye
mov edx, OFFSET goodBye
call WriteString
call CrLf
invoke ExitProcess,0
main endp
end main
我的错误是这样的：
