我如何输出用户输入的字符串

Question

我是 LC-3 汇编语言的新手，目前正在做作业，其中一个问题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

我希望用户输入字符串后，程序会显示结果。我该如何解决这个问题？
