perl arguments
 

OK I'm a newbie at perl. whats wrong with the perl below??? I keep getting errors

Global symbol "$hostfile" requires explicit package name at ./multi-rtr-cmd.pl line 14.
Global symbol "$outputfile" requires explicit package name at ./multi-rtr-cmd.pl line 16.
Global symbol "$command1" requires explicit package name at ./multi-rtr-cmd.pl line 18.
Global symbol "$command2" requires explicit package name at ./multi-rtr-cmd.pl line 20.
Global symbol "$outputfile" requires explicit package name at ./multi-rtr-cmd.pl line 31.



These are being generated by the piece of script below.
I've tried all sorts of different quotes and reading various bits.
Please help me on my learning path.

# Read in the arguments into script variables

if(!"@ARGV"){&Usage};

if($ARGV[0] eq "-i") {$hostfile = "$ARGV[1]"};

if($ARGV[2] eq "-o") {$outputfile = "$ARGV[3]"};

if($ARGV[4] eq "-c1") {$command1 = "$ARGV[5]"};

if($ARGV[6] eq "-c2") {$command2 = "$ARGV[7]"};

TIA,
Neil.

It looks like you have "use strict;" You will need to declare the variables with:
my $varname;
