Perl cmds doesn't work in Bash shell . Plz help

Hi everyone,
I have a Linux OS in my PC (older version 9). Its default shell is bash. Whenever I try to run some Perl program it throws error ! eg, if I run this simple PERL program ,

#!/usr/bin/perl

printf "\lHello \n";

$var=3 ;
printf $var;

@list=(1,2,3);
printf "@list";
------------------------ it says -
in Bash =3 command is not found and the last two lines have syntax error !
Smilie
I tried it in cygwin also & got the same error (its default shell is also bash). But in my Office -PC, no error is observed.
How to tackle with this situation? should I get the latest version of Linux on which PERL can run without error ?
Please help.

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
