VisualStudio2015汇编程序一次写入所有字符串？

Question

我正在编写一个接受输入的程序，然后将其从一个长度单位转换为另一个指定的长度单位。问题是我的代码是在命令提示符的同一行上一次打印每个字符串，一旦输入值和转换，它就会退出而不是显示值。这是代码（我是ASM的新手，准备好你的眼睛）：

include Irvine32.inc    

.data
len Dword ?
InL Dword ?
str5 Byte "Enter the value of your length"
str6 Byte "1 for Yards to feet, 2 for feet to inches, 3 for yards to inches"
str7 Byte "Your converted output is:"

.code
main proc
  lea edx, str5
   call WriteString
   call ReadDec ;prompts for a value and stores it as len
   mov len, eax
  lea edx, str6
   call WriteString
   call ReadDec
   mov InL, eax

   cmp InL, 2 ;prompts your conversion and compares it to send you to the right converter.
   jl YardsFeet
   je FeetInches
   jg YardsInches

YardsFeet:
 mov eax, 3
 MUL len
 jmp LenOut
FeetInches:
 mov eax, 12
 MUL len
 jmp LenOut
YardsInches:
 mov eax, 36
 Mul len
 jmp LenOut
LenOut:
mov eax, len
 lea edx, str7
 call WriteString
 Call WriteDec
 call crlf
exit
main endp
end main

我觉得这可能是一件很简单的事情我可以忽视，但最近大部分都是这样的。
