Plus, on a POSIX compliant system :

Code:

int main()
{
	return 42001;
}

Code:

$ cc -o testc test.c
$ testc
$echo $?
17

because 42001 % 512 = 17. There is a max value allowed for return codes. So, if the OP has several thousand records the value will be meaningless.

Return codes are for program status.
