I haven't tested this or anything, but this is the direction I'd go if I were writing it:

#!/usr/bin/perl -w
use strict;

print "Content-type: text/html\n\n";

my @locmap = (  
#         Loc   Prefix      NW N NE W E SW S SE
        [ 'LA', '1LA', [ qw{     NE   E SW S SE} ] ],
        [ 'LB', '2LB', [ qw{NW   NE W   SW     } ] ],
        [ 'LC', '3LC', [ qw{            SW S SE} ] ],
        [ 'LD', '4LD', [ qw{            SW S SE} ] ],
);
my $c_position;

foreach my $L (@locmap) {
  my $location = $$L[0]; # LA, LB, etc
  my $out = $$L[1];      # Prefix value to output
  my @locs = @{$$L[2]};  # Compass directions for this location

  my $locs = substr $test_loc, 6,2;
  $locs=~s/\s+//;

   if ( grep { $locs eq $_ } @locs ) {
     $c_position=$c_position. " $out= ".join('|',@locs)
   }
   else {
     $c_position=$c_position." 5ALL OTHERS HERE.";
   }
}
print "Results= $c_position\n\n";
