我如何输出用户输入字符串

Question

我对LC-3汇编语言很陌生，目前正在做作业，我要问的问题之一是输出用户输入的字符串，例如：

Please enter a text: Hello world123

The text you have entered is: Hello world123

这是我一直在使用的代码：

.orig x3000

Lea r0, Name

Puts

Lea r0, inputstring

Puts

lea r2, outputstring

loop

getc

add r1,r0, -10

brz outside

out

str r0,r2, #0

add r2, r2, #1

brnzp loop

outside 

lea r0, output_text

puts

Halt

Name .stringz "Francois Van Zyl"

inputstring .stringz "\nPlease enter a text: "

output_text .stringz "\nThe text you have typed is: "

outputstring .blkw 99

.end

我希望在用户输入字符串之后，程序将显示结果。我该如何解决？
