Mips how to store user input string

Question

I used to think I knew how to do this  But then I actually tried to do it  Here s the program I wrote but the Berkeley S    simulator for mac said there was a syntax error on the last line  What did I do wrong           text         globl   start       start          la  a0 ask         li  v0 4         syscall          li  v0 8         syscall          la  t0 buffer         move  t0  v0         syscall          la  a0 ret         li  v0 4         syscall          move  a0  t0         li  v0 4         syscall           data       ask    asciiz  Enter string          ret    asciiz  You wrote          buffer     space 100

This code works fine in QtSpim simulator   data     buffer   space 20     str1    asciiz  Enter string      str2    asciiz  You wrote  n    text  main      la  a0  str1      Load and print string asking for string     li  v0  4     syscall      li  v0  8         take in input      la  a0  buffer    load byte space into address     li  a1  20        allot the byte space for string      move  t0   a0     save string to t0     syscall      la  a0  str2      load and print  you wrote  string     li  v0  4     syscall      la  a0  buffer    reload byte space to primary address     move  a0   t0     primary address   t0 address  load pointer      li  v0  4         print string     syscall      li  v0  10        end program     syscall

Ok  I found a program buried deep in other files from the beginning of the year that does what I want  I can t really comment on the suggestions offered because I m not an experienced spim or low level programmer Here it is             text           globl   start       start           la  a0 str1  Load and print string asking for string          li  v0 4          syscall           li  v0 8  take in input          la  a0  buffer  load byte space into address          li  a1  20   allot the byte space for string          move  t0  a0  save string to t0          syscall           la  a0 str2  load and print  you wrote  string          li  v0 4          syscall           la  a0  buffer  reload byte space to primary address          move  a0  t0   primary address   t0 address  load pointer           li  v0 4   print string          syscall           li  v0 10  end program          syscall                   data              buffer   space 20              str1    asciiz  Enter string max 20 chars                  str2    asciiz  You wrote  n                                                             Output                Enter string max 20 chars   qwerty 123               You wrote                qwerty 123               Enter string max 20 chars     new world oreddeYou wrote                  new world oredde   lol special character
