error A2013: .MODEL must precede this directive

Question

Tinkering around with MASM a bit, and I have no idea what these errors mean, or if I'm writing this code close to correctly. As it is written currently, it should just be greeting the user, asking for two numbers and saying goodbye (trying to get a skeleton working before doing any calculations or anything special).

INCLUDELIB Irvine32.inc ;  Note: line number 7


.data
userName    BYTE    33 DUP(0)   ;string to be entered by user
firstNumber DWORD   ?           ;integer to be entered by user
secondNumber    DWORD     ?         ;integer to be entered by user
intro_1     BYTE        "Elementary Arithmetic by Marshall Todt", 0
intro_2     BYTE        "Enter 2 numbers, and I'll show you the sum, difference,", 0
intro_3     BYTE        "product, quotient, and remainder.", 0
prompt_1        BYTE        "Enter the first integer: ", 0
prompt_2        BYTE        "Enter the second integer: ",0
goodBye     BYTE        "Impressed?  Bye!", 0

.code
main PROC

;Introduction
    mov     edx, OFFSET intro_1 
    call    WriteString
    call    CrLf
    move        edx, OFFSET intro_2
    call WriteString
    call CrLF
    move        edx, OFFSET intro_3
    call WriteString
    call CrLF

;Get the data
    mov     edx, OFFSET prompt_1
    call    WriteString
    call    ReadInt
    mov     firstNumber, eax
    mov     edx, OFFSET prompt_2
    call    WriteString
    call    ReadInt
    mov     secondNumber, eax



;Say "Good-bye"
    mov     edx, OFFSET goodBye
    call    WriteString
    call    CrLf
    exit    ; exit to operating system
main ENDP

END main

These are the errors i am getting:

Answer 1

You need .model flat at the beginning of the code - and probably .486 before that as well. I think that will fix almost all of your problems.

Answer 2

You can also avoid this if you use x64 as the Platform instead of x86. As you are using the 64 bit x registers in your code maybe you are coding for x64!!!
