Greetings Monks

This was inspired by a recent technique for frequency analysis
using hash references.I was curious if the same could be
accomplished by using only lists. The following code is the
result of creative kludge and insight into three dimensional
data structures.

#! /usr/bin/perl -w
our @frequency;
our @words;

print "Which file requires frequency analysis please?\n";
$phile=<STDIN>;
open(PHILE, "+< $phile")
||die "File specified can not be accessed:$!\n";

while (@interval=<PHILE>){
    foreach $line(@interval){
    chop $line;
    @werdz=split(/ / ,$line);
    $space=@werdz;
    analyize($space,@werdz);
                }
}
$initialize="abcdefghijklmnopqrsstuvwxyz";
unshift @words,$initialize;
@alpha=alphatrans();

for $word(@words){
    $lengh=@word;
    @letters=split (//, $word);
    foreach $key(@letters){
            $key=uc $key;
            frequency($key);
                            }  
}

for $row(@frequency){
    $lengh= @$row;
    $unit=$lengh-1;
    $token=shift @alpha; 
        print " $token= $unit //// ";
    }

sub analyize{
    push @words, @werdz;
    }


sub frequency{
$key=pop @_;
 for$i(0...25){    
    if( $alpha[$i] eq $key ){
    push @{$frequency[$i]},$key;
                                 }
              }
}

sub alphatrans{
 our @nums;
 our @pass1;
               
        foreach $k(0...25){
        $i=$k;
        push (@nums, $k);
        $k=~ tr/0-9 /A-J/ ;
        push (@pass1, $k);
                          }
    
        foreach $bdiad(@pass1){
                if  ($bdiad=~/B(.+)/){
                push (@b,$bdiad);
                                      }
        }
            foreach $cdiad(@pass1){
                if  ($cdiad=~/C(.+)/){
                push (@c,$cdiad);
                                     }
        }
                 foreach $y (0..9){
                 $f=shift @b;
                 $f=$y ;
                 $y=~ tr/0-9/KLMNOPQRST/ ;
                 push (@blist, $y );
                                   }
                foreach $x (0..5){
                 $g=shift @c;
                 $g=$x ;
                 $x=~ tr/0-5/UVWXYZ/ ;
                 push (@clist,$x );
                                 }
                splice (@pass1, 10, 10,@blist);
                splice (@pass1, 20, 6, @clist);
       return @pass1;
