Well, I've used the code corian posted. And, o course, it works perfectly. Except, I edited it in places, and now wierd stuff happens. :(. Basically, when I use the -c or -r option, it works great. But when I use the -a option, it tells me I've left off the option, but doesn't give me the error until AFTER it prints SOME of the data. Strange. The other thing is, why does the order change everytime the script is run? 
#!/usr/bin/perl -w
use strict;

my $infile = $ARGV[0];
my $act = $ARGV[1];
my $included = "n";
my $lvar ="";
my @validchars = ("A", "B", "C", "D", "E", "F", "G", "H",
 "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S",
  "T", "U", "V", "W", "X", "Y", "Z");

if ($#ARGV < 1) {
  print "Usage: $0 <file> <chars>
  Where <chars> can be -a or -c:
       -a: show all charactors. (ie, spaces, etc.)
       -c: show only regular charactors, but keep case. (ie, x is diff
+erent than X.)
       -r: show only regular charactors, disregard case. (ie, t and T 
+are the same.)\n";
  exit;
}

my $count = 0;

system("cls");   #win
system("clear"); #*nix

open INPUT, "<$infile" or die "Couldn't open '$infile' : $!";
my $input = do { local $/; <INPUT> };

my %histogram;

for my $char (split //, $input) {
  $included = "n";

  if ($act eq "-a") {
    $histogram{$char}++;
    $count++;
  } elsif ($act eq "-c") {
    foreach $lvar (@validchars){
      if ($lvar eq uc($char)) {$included = "y";}
    }
    if ($included eq "y") {
      $histogram{$char}++;
      $count++;
    }
  } elsif ($act eq "-r") {
    foreach $lvar (@validchars){
      if ($lvar eq uc($char)) {$included = "y";}
    }
    if ($included eq "y") {
      $histogram{uc($char)}++;
      $count++;
    }
  } else {
    print "Bad charactor option: '$act'.\n";
    exit;
  }
};

print "Of $count charactors:\n\n";

for (keys %histogram) {
  if ($_ eq "\n") { print "'\\n' occurred $histogram{$_} times. (".(($
+histogram{$_}/$count)*100)."%)\n"}
  else { print "'$_'  occurred $histogram{$_} times. (".(($histogram{$
+_}/$count)*100)."%)\n" }
};
