I have some Perl script that was running fine for months, but recently has stopped working. Does anyone know if something been changed by PowWeb?

print "content-type: text/plain\n\n";
open(DAT, "myData.txt") ;
while (<DAT>) {
print $_;
close (DAT);
exit 0;

The above code used to print null if the file doesn't exist. Now it prints "0". This change in behavior really throws off the code that handles the output from this script.

Any help anyone has would really be appreciated!
