# simple example of returning a value from a function
# note storing of return address $ra

# code for function main
main:
    begin               # move frame pointer
    push  $ra           # save $ra onto stack

    jal   answer        # call answer(), return value will be in $v0

    move  $a0, $v0      # printf("%d", a);
    li    $v0, 1        #
    syscall             #

    li    $a0, '\n'     # printf("%c", '\n');
    li    $v0, 11       #
    syscall             #

    pop   $ra           # recover $ra from stack
    end                 # move frame pointer back

    li    $v0, 0        # return
    jr    $ra           #


# code for function answer
answer:
    li   $v0, 42        # return 42
    jr   $ra            #
