I am trying to do some basic formatting for specific output that is being parsed from top. However, I have a syntax error on line 52, near "." I am using perl 5.10.1

I'm sure I am missing something obvious, but I am relatively new with perl and the manual pages don't appear to offer an obvious explanation. I have tried a few other places for the format code, but I continually get the "." syntax error.

#!/usr/bin/perl
use strict;
use warnings;
use English;
#use FileHandle;

## Declarations ##
my @topps = qx/top -b -n 1/;
my @iostatc = qx/iostat -t -m/;
my @iostatd= qx/iostat -m -x | grep -v Linux/;
my @top;
my @topout;
## End Delcarations ##

## Grab top ps info on any processes using cpu ##
foreach (@topps) {
    chomp;
    if ($_ =~ /^(\s)*\d+.*/) { 
    push @top, $_;
    }
    elsif ($_ =~ /^.*:.*/) {
    # Print out tops header info
    print "$_\n";
    }
}

# Some simple headers
#my @tophat = ( "User", "Command", "CPU%", "Mem%" );
#$topout[0] = [ @tophat ];

foreach (@top) {
    my $i = 0;
    my @line = split;
    if ($line[8] != 0) {
    my @tmp = ( "$line[1]", "$line[11]", "$line[8]%", "$line[9]%" );
    $topout[$i] = [ @tmp ] ;
    }
    $i++;
}

## End top grab ##

## Format and Print the top info ##

foreach my $t (@topout) {
    my $index = 0;
    foreach my $ps (@$t) {
        my $user; my $cmd; my $cpu; my $mem;
format STDOUT_TOP = 
@<<<<<<<<<<<<<<<     @||||||||||    @|||||    @|||||
User                  Command        CPU%      Mem%
.
$^ = 'STDOUT_TOP';
format STDOUT = 
@<<<<<<<<<<<<<<<     @||||||||||    @#####    @#####
$user,                $cmd,          $cpu,     $mem
.
$~ = 'STDOUT';
        if ($index == 0) {
          $user = "$ps";
        }
        elsif ($index == 1) {
          $cmd = "$ps";
        }
        elsif ($index == 2) {
          $cpu = "$ps";
        }
        elsif ($index == 3) {
          $mem = "$ps";
        }
       $~ = 'topinfo';
       write;
       $index++;
    }
}

## iostat cpu and device info ##
sub bang {
    for my $i (1..80) {
    print "#";
    }
    print "\n";
}
bang();
foreach (@iostatc) {
    chomp;
    print "$_\n";
}
bang();
foreach (@iostatd) {
    chomp;
    unless ($_ =~ /^[(avg.*)|(\s+\d+.*)]/) {
    unless ($_ =~ /^\d+/) {
        print "$_\n";
    }
    }
}
bang();

Any suggestions are improvements are welcome in addition to solving the formating error.

Thanks.
