Thanks for the link! It took me back on track again.

But...

I got that I should use the cdq instruction to extend the eax to edx. Right?

Am I thinking correct if I try using this rewritten code instead of the old one?

(Toggle Plain Text)

_gluLookAt macro A1, A2, A3, A4, A5, A6, A7, A8, A9
	mov eax, A9
	cdq
	push eax
	push edx

	mov eax, A8
	cdq
	push eax
	push edx

	...

	mov eax, A1
	cdq
	push eax
	push edx

	call gluLookAt
endm
