assembly - 运行代码时出现错误 MIPS “spim: (parser) syntax error”

Question

我正在使用 MIPS 模拟器。

当我尝试在模拟器中打开包含我的代码的文本文件时发生

我无法理解为什么它不能在 QTSpim 上运行。我得到错误

spim: (parser) syntax error line 8

代码:

#This program read the given array value one by one
#then compare and find largest
#Display largest and it's count

#Data declaration

这在 MARS 上运行，我不确定为什么它不能在 QTSpim 上运行。

Answer 1

a: .word 5,2,15,3,7,15,8,9,5,2,15,3,7

用空格替换,。mips 不会占用 ,

试试这个:

a: .word 5 2 15 3 7 15 8 9 5 2 15 3 7
