# right code...

          .data 
str1:     .asciiz "please enter two numbers:\n" # when I change 'please' to 'plz', something wrong happends! why?
str2:     .asciiz "the Result:\n"
str3:     .asciiz "Waring:result overflow!\n"
CONTROL:  .word32 0x10000
DATA:     .word32 0x10008


    .text
main:
    lwu r21,CONTROL(r0)
      lwu r22,DATA(r0)
    daddi r24,r0,4        ;set string output
    daddi r1,r0,str2      ;get address of str1
       sd r1,(r22)        ;wirte DATA
       sd r24,(r21)       ;print

    halt

我想在 winmips64 上打印一个字符串。它在错误代码中不显示任何内容，但在正确代码中有效。在正确的代码中，我尝试在 str1 中将 'please' 更改为 'plz' 并且它不再起作用，为什么？
