Question No 5
1. Assume that the following variables have been defined:
.data
val1 dw 2000h val2
dw1000h val3 dw 0
The following statements call a procedure named Exchange, using stack parameters:
push offset val1 push
offset val2
call Exchange
add sp,4
The Exchange procedure exchanges the values of val1 and val2, so that after the call,
val1 equals 1000h and val2 equals 2000h. Here is the beginning of Exchange: Exchange
proc Exchange
push ebp
mov ebp,esp
What instructions should occur next in the Exchange procedure to complete the exchange of
the values inside the two variables that were passed to this function?
