The ArraySum procedure discussed below receives a pointer to any array of doublewords:

ArraySum PROC

mov esi,$0$ ; array index

mov eax, $0$ ; set the sum to zero

mov ecx,LENGTHOF myarray ; set number of elements

L$1$: add eax,myArray$[$esi$]$ ; add each integer to sum

add esi,$4$ ; point to next integer

loop L$1$ ; repeat for array size

mov theSum,eax ; store the sum

ret

ArraySum ENDP

depends on the prior value stored in ESP

FALSE

TRUE

depends on the prior value stored in ESX
