I'm using a MIPS simulator.
Occurs that when I'm trying to open the text file that contains my code in the simulator
I am having trouble understanding why this will not run on QTSpim. I get the error
spim: (parser) syntax error line 8
Code:
#This program read the given array value one by one
#then compare and find largest
#Display largest and it's count
#Data declaration
.data
a: .word 5,2,15,3,7,15,8,9,5,2,15,3,7 #Initialize an array

nextLine: .asciiz "\n" #for \n
big: .asciiz "bigger....\n" #Display bigger
small: .asciiz "smaller....\n" #Display smaller
equal: .asciiz "same....\n" #Display same
#Output display strings
Largest: .asciiz "The largest number is "

This runs on MARS and I'm not sure why it wont run on QTSpim as well.
