[MacPerl] subroutine parameters - elementary question

["Noe Dinnerstein: President, BodhiSoftWare" <norbu108@tuna.net>]

I'm having dificulty getting the correct syntax for passing and using a
filename as a parameter to a subroutine which will then open and read it.
I have be fiddling with different ways to deal with scope, but this is
fairly new territory for me and I'm probably overlooking something
obvious....

A synopsis of the code:

#!perl -w

#
use strict;
use Mac::Windows;
use Mac::QuickDraw;
use Mac::Events;
use Mac::StandardFile;
use Mac::Dialogs;
#******************************************************
my($DoSearch,$dlg);

$DoSearch = 0;

ShowDialog();
while ($dlg->window() ) {
  $dlg->modal();
}

if ($DoSearch == 1) {
	SearchDirs();
}
dispose $dlg;

#***************************************************
sub ShowDialog {


#------ SET UP DIALOG FOR SEARCH
#etc
.
.
.

#THE HEART OF THE MATTER

sub SearchDirs()
  {

      my $myDisk = 'DorjeJigje';
    print ("\nroot volume -  $myDisk:\n");
     my $rootdir = "$myDisk:Technical Mail, etc";
    opendir(DIR, $rootdir) or die "cannot open $myDisk";
    my @files = readdir(DIR);
    foreach my $file (@files)
    {
         print("$file\n");
        my $newdir = $rootdir . $file;
        opendir(NEWDIR,$newdir);

        my @newfiles = readdir(NEWDIR);
        foreach my $newfile(@newfiles) {

               if (-B $newfile) {
                  print "" ;
    						     }
               elsif (-d $newfile)	{
                  print "";
               }
               else {

                SearchFile($newfile, $dlg->item_text(4));  #HERE'S WHERE
THE TROUBLE STARTS
               }
    				      }

     }
   closedir(DIR);

 }


#HERE'S WHERE THE PROBLEM LIES

sub SearchFile(main::$newfile, $dlg->item_text(4)) {
    my $openFlag = 0;
    my $searchString = $dlg->item_text(4);
    open(IN,main::$newfile) or die  ("Can not open file\n"); #I GET THE
FOLLOW MESSAGE AT THIS LINE


# Bad name after SearchDirs::.
File 'DorjeJigje:Programming:MacPerl Ÿ:Noe's Perl Stuff:ReadDirs.pl '; Line 130


    while main::$line = <IN> {
          if ( $line =~ m/$searchString/ ) {
             if $openFlag == 0 {
                $openFlag = 1;
                print ("\t $file \n");
                print ("\t\t $line \n");

              }
              else {
                print ("\t\t $line \n");
              }

          }
    }
    close (IN);
}

Any pointing out the obvious would be welcome......
