Hey RollyGuy
thanks again for all your help. Your code works perfectly and I nearly have it integrated into ma program. But could you (or anybody else) tell me whats wrong with the code below.?
Thanks

#!/usr/bin/perl

use strict;

my @views = ( 'view0', 'view1');
my $num_of_views = scalar(@views);
my %hash;
my @global_include = ("size, buffersize, value", "size, buffersize, va
+lue");
my $lastview;
my $output;

for (my $j = 0; $j < $num_of_views; $j++){
   my @array = split (", ",$global_include[$j]);
   pop @array;
   $hash{$j} = \@array;
}

#for (my $j = 0; $j < $num_of_views; $j++){
#   my $ref = $hash{$j};
#   print "HASH CONTAINS FOR $j: ";
#   foreach (@$ref){
#        print "$_\n";
#   }
#}

foreach my $key (sort(keys %hash)){
    # Do this only the first time.
    if(not defined($lastview)){
    $lastview = $key;
    $output = "$key";
    next;
    }

    $output .= " full outer join $key on ";
    my $i;
    my $array_elements_used = scalar(@{ $hash{$key} })-1;
    #loop through all of the elements except for the last
    for($i=0;$i<$array_elements_used;$i++){
    $output .= "$lastview.$hash{$lastview}[$i] = $key.$hash{$key}[$i]"
+;
    # only add an "and" if this is not the last element used.
    $output .= " and " if ($i != ($array_elements_used-1));
    }
    $lastview = $key;
}
print $output, "\n";

In your for loop that creates the hash, you are using just $j as the key to the hash. That will result in the keys just being numbers. You actually want the keys to be the values in the array @views that correspond to the entry $j. So you will need to change:
$hash{$j} = \@array;
into
$hash{$views[$j]} = \@array;

As an additional note, the perl debugger will easily print out structures like hashes so that you can ensure they are created properly. Use the command 'perldoc perldebug' to read the documentation when you get a chance.
