Hi Rory,
Assuming that if there is a problem in opening the file then it's 0, I
hope the following code helps.
#Code Begings
if (open (INFILE, "<file.txt")) {
$flag = <INFILE>;
close (INFILE);
} else {
$flag = 0;
}
if ($flag == 0) {
$flag = 1;
} else {
$flag = 0;
}
open (OUTFILE, ">file.txt") || die;
print OUTFILE $flag;
close (OUTFILE);
#Code Ends
Regards,
Ahmed
