Assembly Array absoluten Wert

Question

Ich versuche Assembly-Prozedur zu schreiben, die einen Parameter im Register ebx empfängt, und gibt den absoluten Wert des Parameters im Register eax, dann ruft diese Prozedur in einer Schleife alle Elemente eines bestimmten Arrays und um ihre absoluten Werte zu erhalten. Wenn ich den Code ausführe, erhalte ich die folgenden Segmentfehler von Assembler.

Ich brauchte die ABS Verfahren nach dem .CODE Abschnitt zu bewegen:

INCLUDE Irvine32.inc 

.DATA 

arrayW SDWORD 3, -2, 5, 7, 2, 9, -11, 32, -19, 18, 17, 15, -5, 2, 3, 1, -21, 27,-29, 20 


.CODE 

ABS PROC 
    cmp ebx,0  ;compare ebx to zero 
    jle L1   ;Jump if less then or equal to zero 
    mov eax, ebx ;copy ebx to eax, means eax is positive 
    jmp L2   ;jumps to label return 
    L1:neg ebx  ;negates ebx  
    mov eax,ebx  ;copy neagted ebx to eax   
    L2:ret 
ABS ENDP 

main PROC 

    mov esi, OFFSET arrayW  ;address of arary 
    mov ecx, LENGTHOF arrayW ;loop counter 

top: 
    mov ebx,[esi]    ;move first element of arrayw to ebx 
    call ABS     ;calls procedure abs and gets the eax value 
    call Writeint    ;displays eax 
call Crlf 
    add esi, TYPE arrayW  ;points next element in array 
    loop top     ;loop goes to the top 

    exit 
main ENDP 

END main
