### A good answer might be:

Yes.

# A Fine Example

Sometimes you will have to remove the null at the end of the input string, perhaps because it is intended to be part of a larger string. Other times, as in the following example, you can use two print string operations.

The example program asks the user to enter a person's name followed by comma and "enter". Then the program writes out a personalized letter using the name. The body of the letter is printed using only one `syscall`. The personalized greeting is printed first in a separate `syscall` because it is null terminated.

    # overdue.asm

            .text
            .globl  main

    main:
            # get patron name
            li      $v0,4           # print prompt
            la      $a0,prompt      #
            syscall
            li      $v0,8           # code 8 == read string
            la      $a0,name        # $a0 == address of buffer
            li      $a1,24          # $a1 == buffer length
            syscall                 # Invoke the operating system.

            # print the letter
            li      $v0,4           # print greeting
            la      $a0,letter      #
            syscall
            li      $v0,4           # print body
            la      $a0,body        #
            syscall

            li      $v0,10      # exit
            syscall

            .data
    prompt: .asciiz "enter name, followed by comma-enter: "
    letter: .ascii "\n\nDear "
    name:   .space 24

    body:   .ascii "\nYour library books are way\n"
            .ascii "overdue.  Please return them\n"
            .ascii "before we give your name\n"
            .ascii "to the enforcement squad.\n\n"

    # end of file

It is somewhat crude to make the user enter a comma at the end of the name. It would be nicer to have the program detect the end of the name and automatically put a comma after it. The program would be much longer.

Is "backspace" a character?
