its quite easy, easier than you guys think.

When you an interrupt of level trigger and you cant use for some reason edge trigger interrupts, and dont want the microprocessor attend the same interrupt more than once you must do the next code:

ORG 0
JMP MAIN

ORG 03h
JMP pint0

ORG 13h
JMP pint1

MAIN:

MOV IE,#10000101b; this puts on 1 both external interrupts on ports


pint0:
JNB P3.2,$; polling question, is it 0 yet? doesnt matter how long it will go directly to the code
---------- your code
---------- your code
---------- your code
---------- your code
RETI

pint1:
JNB P3.3,$; polling question, is it 0 yet? doesnt matter how long it will go directly to the code
---------- your code
---------- your code
---------- your code
---------- your code
RETI


Its a waste of time of course but it will be stuck in JNB until it goes HIGH again, and no mistakes will occur.

He said i was right and i have my extra-homework points.

Thank you for all the ideas you guys gave me.
