Question

[MIPS] undefined opcode or wrong number or type of operands at Character 0 in field 2

so here's the code i want to run

.text

main:

#call string bob into a0. syscall prints string in the registor a0 always?

#load address

la $a0, Bob

li $v0, 4

syscall

li $v0, 10

syscall

.data

#store the string in the data segment and add null terminator

Bob: .asciiz "My name is Bob."

And this error keeps occurring

line 5 undefined opcode or wrong number or type of operands at character 0 in field 2

line 7 undefined opcode or wrong number or type of operands at character 0 in field 2

line 10 undefined opcode or wrong number or type of operands at character 0 in field 2

Don't see any wrong with the code. what should I do to fix this?

Answer 1

Note :- try this order. May be the compiler unable to find the string Bob as it is defined later

MIPS PROGRAM :-

   .data
       Bob: .asciiz “My name is Bob”
  
   .text
.globl main
main:
la $a0, Bob
li $v0, 4
   syscall  
  
   li $v0, 10
syscall
