Hi, thank you for the prompt reply. I have fixed the printf part. but it still wouldn't work correct.

[root@local]#cat test.pl
#!/usr/bin/perl
use strict;
use warning;

my $arg00=shift ( @ARGV );
my $arg01=shift ( @ARGV );

#printf $arg00+$arg01."\n";
printf( "%d", $arg00 & $arg01 );

[root@local]#./test.pl 33 224
<BR>22[root@local]#
[download]

It should return 32 but returns 22.
I cant figure out why this happens...
regards,
toro
