I am running a perl script (on Win) which calls C++ exe file, I would like to print out the return value of the C++ exe file

I used -

system("a.exe")
print $?
[download]

either

$retVal = system("a.exe");
print "$retVal\n";
[download]

but both prints:

% C++ retVal : 3
% 256
[download]

Any idea why i get 256 and not 3 ? any solution

___________________________________

C++ code looks -

int main()
{
 cout << "C++ retVal: 3" << endl;
 return 3;
}
[download]

Thanks azaria
