我正在编写一个程序，最终将单词翻译成pig latin，到目前为止，我已将用户输入的字符存储到单独的内存位置（单词最多可以是19个字符）。
现在我想在用户点击回车键时打印另一个提示（在他们用英语输入他们的单词之后）。我看了一些例子，我看到他们在程序底部附近有一行说“NEWLINE .FILL x00A”。我知道这是输入密钥的ASCII代码，但我不知道如何告诉我的程序在点击“Enter”后需要显示另一个提示。任何提示或想法都表示赞赏！

START ST R1,SAVER1

ST R3,SAVER3
LEA R1,PROMPT ; loading the address of the first character of prompt
LOOP LDR R0,R1,#0 ; loading the first character into R0
BRz INPUT ; if at 0, or at the end of the string, (.STRINGZ initializes length+1 memory locations,
; last location being 0), then go to instruction labeles "INPUT"; else go to next instructio
L2 LDI R3,DSR ; loading the display status register into R3
BRzp L2 ; if display status register is not clear (meaning monitor is still processing char), then load DSR again
STI R0,DDR ; store R0 into DDR's memory location
ADD R1,R1,#1 ; increment prompt address so that we can move through the string until the end
BRnzp LOOP ; this will go to the LOOP instruction no matter what
