Friends,

I am having trouble dealing with 0 in certain cases. Here are a few snippts and what bugs me about them.
...
my      $MISC_FILE_DIR  = shift || die usage();
my      $req            = shift || die usage();
my      $inqfile        = shift || die usage();
my      $sent           = shift || die usage();
my      $status         = shift || die "please specify status\n" . usa
+ge();
...

Zero is a valid value for status but how do I keep it from be treated like undef? Here's what happens when I use zero on the command-line. 
bash-2.03$ insertIntoLN.pl misc 135 doesnt_matter 20031208120000 0
please specify status
usage: ./insertIntoLN.pl <miscdir> <req> <inqfile> <sent> <status>

Also when I pull data out of the database zero seem to be treated as undef. Example) 
...
while( my @row = $sth->fetchrow_array ) {
        print join( '|', map ( $_ || 'NULL', @row )) ."\n";
}
...

Output I get is ... 
137|src/20031208153031.txt|20031210093234|NULL|NULL
138|src/20031208153031.txt|20031210093509|NULL|NULL

... I was expecting the last column to be 0. What am I not getting here?
Thanks
